The `format` variable here is `\"%%\"`. At this point, it is safe to access `*(format + 2)` but not safe to access `*(format + 3)`.\n\n```c\nfor (p=strchr(format,'%'); p != (char *) NULL; p=strchr(p+1,'%'))\n{\n q=(char *) p+1;\n if (*q == '%')\n {\n p=q+1;\n continue;\n }\n```\n\nThe 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`).\n\nIn the next iteration, `p + 1` (`format + 3`) is passed to `strchr`, and when `strchr` accesses it, this causes an out-of-bounds read.",

stack buffer overflow and would like to report this issue.\nCould you confirm if this qualifies as a security vulnerability? I am happy to provide any additional information needed.\n\n## Summary\n\nIn 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()`.\n\n### Additional information\n\n 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.\n\nFurthermore, 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.\n\n## Details\n\n- **Vulnerability Type:** CWE-124: Buffer Underwrite\n- **Affected Component:** MagickCore/image.c - Format processing within InterpretImageFilename()\n- **Affected Version:** ImageMagick 7.1.1-47 (as of commit 82572afc, June 2025)\n- **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.\n\n## Reproduction\n\n### Tested Environment\n\n- **Operating System:** Ubuntu 22.04 LTS\n- **Architecture:** x86_64\n- **Compiler:** gcc with AddressSanitizer (gcc version: 11.4.0)\n\n### Reproduction Steps\n\n```bash\n# Clone source\ngit clone --depth 1 --branch 7.1.1-47 https://github.com/ImageMagick/ImageMagick.git ImageMagick-7.1.1\ncd ImageMagick-7.1.1\n\n# Build with ASan\nCFLAGS=\"-g -O0 -fsanitize=address -fno-omit-frame-pointer\" CXXFLAGS=\"$CFLAGS\" LDFLAGS=\"-fsanitize=address\" ./configure --enable-maintainer-mode --enable-shared && make -j$(nproc) && make install\n\n# Trigger crash\n./utilities/magick mogrify %d%d\n```\n\n### Output\n\n```plaintext\n==4155==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7ffda834caae at pc 0x7f1ea367fb27 bp 0x7ffda834b680 sp 0x7ffda834ae10\nWRITE of size 2 at 0x7ffda834caae thread T0\n #0 0x7f1ea367fb26 in __interceptor_vsnprintf ../../../../src/libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc:1668\n #1 0x7f1ea2dc9e3e in FormatLocaleStringList MagickCore/locale.c:470\n #2 0x7f1ea2dc9fd9 in FormatLocaleString MagickCore/locale.c:495\n #3 0x7f1ea2da0ad5 in InterpretImageFilename MagickCore/image.c:1696\n #4 0x7f1ea2c6126b in ReadImages MagickCore/constitute.c:1051\n #5 0x7f1ea27ef29b in MogrifyImageCommand MagickWand/mogrify.c:3858\n #6 0x7f1ea278e95d in MagickCommandGenesis MagickWand/magick-cli.c:177\n #7 0x560813499a0c in MagickMain utilities/magick.c:153\n #8 0x560813499cba in main utilities/magick.c:184\n #9 0x7f1ea1c0bd8f in __libc_start_call_main ../sysdeps/nptl/libc_start_call_main.h:58\n #10 0x7f1ea1c0be3f in __libc_start_main_impl ../csu/libc-start.c:392\n #11 0x560813499404 in _start (/root/workdir/ImageMagick/utilities/.libs/magick+0x2404)\n\nAddress 0x7ffda834caae is located in stack of thread T0 at offset 62 in frame\n #0 0x7f1ea2c60f62 in ReadImages MagickCore/constitute.c:1027\n\n This frame has 2 object(s):\n [32, 40) 'images' (line 1033)\n [64, 4160) 'read_filename' (line 1029) <== Memory access at offset 62 underflows this variable\nHINT: this may be a false positive if your program uses some custom stack unwind mechanism, swapcontext or vfork\n (longjmp and C++ exceptions *are* supported)\nSUMMARY: AddressSanitizer: stack-buffer-overflow ../../../../src/libsanitizer/sanitizer_common/sanitizer_common_interceptors.inc:1668 in __interceptor_vsnprintf\nShadow bytes around the buggy address:\n 0x100035061900: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00\n 0x100035061910: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00\n 0x100035061920: 00 00 00 00 00 00 00 00 f3 f3 f3 f3 f3 f3 f3 f3\n 0x100035061930: f3 f3 f3 f3 f3 f3 f3 f3 00 00 00 00 00 00 00 00\n 0x100035061940: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00\n=>0x100035061950: f1 f1 00 f2 f2[f2]00 00 00 00 00 00 00 00 00 00\n 0x100035061960: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00\n 0x100035061970: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00\n 0x100035061980: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00\n 0x100035061990: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00\n 0x1000350619a0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00\nShadow byte legend (one shadow byte represents 8 application bytes):\n Addressable: 00\n Partially addressable: 01 02 03 04 05 06 07 \n Heap left redzone: fa\n Freed heap region: fd\n Stack left redzone: f1\n Stack mid redzone: f2\n Stack right redzone: f3\n Stack after return: f5\n Stack use after scope: f8\n Global redzone: f9\n Global init order: f6\n Poisoned by user: f7\n Container overflow: fc\n Array cookie: ac\n Intra object redzone: bb\n ASan internal: fe\n Left alloca redzone: ca\n Right alloca redzone: cb\n Shadow gap: cc\n==4155==ABORTING\n```\n\n### Affected Code\n\nIn `MagickCore/image.c`, within the `InterpretImageFilename()` function:\n\n```c\nMagickExport size_t InterpretImageFilename(const ImageInfo *image_info,\n Image *image,const char *format,int value,char *filename,\n ExceptionInfo *exception)\n{\n...\n for (p=strchr(format,'%');

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.\n\nAs 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.\n\nThis causes `vsnprintf()` to write outside the stack buffer range, which is detected by AddressSanitizer as a `stack-buffer-overflow`.\n\n## Proposed Fix\n\nIn `MagickCore/image.c`, within the `InterpretImageFilename()` function:\n\n```c\nMagickExport size_t InterpretImageFilename(const ImageInfo *image_info,\n Image *image,const char *format,int value,char *filename,\n ExceptionInfo *exception)\n{\n...\n /*--------Changed--------*/\n ssize_t\n field_width,\n offset,\n written; // Added\n /*--------Changed--------*/\n...\n for (p=strchr(format,'%'); p != (char *) NULL; p=strchr(p+1,'%'))\n {\n q=(char *) p+1;\n if (*q == '%')\n {\n p=q+1;\n continue;\n }\n field_width=0;\n if (*q == '0')\n field_width=(ssize_t) strtol(q,&q,10);\n switch (*q)\n {\n case 'd':\n case 'o':\n case 'x':\n {\n q++;\n c=(*q);\n *q='\\0';\n written = FormatLocaleString(filename+(p-format-offset),(size_t)\n (MagickPathExtent-(p-format-offset)),p,value);\n /*--------Changed--------*/\n if (written <= 0 || written > (MagickPathExtent - (p - format - offset)))\n return 0;\n offset += (ssize_t)((q - p) - written);\n /*--------Changed--------*/\n *q=c;\n (void) ConcatenateMagickString(filename,q,MagickPathExtent);\n canonical=MagickTrue;\n if (*(q-1) != '%')\n break;\n p++;\n break;\n }\n case '[':\n {\n ...\n }\n default:\n break;\n }\n }\n```\n- 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.\n- Correction is performed according to the actual template structure, ensuring stable behavior regardless of format length without relying on static constants.\n- Range checking of `written` allows detection of vsnprintf failures and excessive writes.\n\n### Commits\nFixed in

Details**\n\nThe magnified size calculations in `ReadOneMNGIMage` (in `coders/png.c`) are unsafe and can overflow, leading to memory corruption.\n\nThe source snippet below is heavily abbreviated due

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.\n\nWhen 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.\n\nThis issue leads to an out-of-bounds write of controlled data beyond the bounds of a heap allocation.\n\nTriggering 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`).\n\n## **Affected Version(s)**\n\nVerified on current HEAD (305e383c8ac7b30bc2ee96ab8c43ec96217ec2a9) and latest stable

scanline stride → heap buffer overflow\n## Summary\n\nA 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.\n\n- **Impact:** Attacker-controlled heap out-of-bounds (OOB) write during conversion **to BMP**.\n \n- **Surface:** Typical upload → normalize/thumbnail → `magick ... out.bmp` workers.\n \n- **32-bit:** **Vulnerable** (reproduced with ASan).\n \n- **64-bit:** Safe from this specific integer overflow (IOF) by arithmetic, but still add product/size guards.\n \n- **Proposed severity:** **Critical 9.8** (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).\n \n\n---\n\n## Scope & Affected Builds\n\n- **Project:** ImageMagick (BMP writer path, `WriteBMPImage` in `coders/bmp.c`).\n \n- **Commit under test:** `3fcd081c0278427fc0e8ac40ef75c0a1537792f7`\n \n- **Version string from the run:** `ImageMagick 7.1.2-0 Q8 i686 9bde76f1d:20250712`\n \n- **Architecture:** 32-bit i686 (**`sizeof(size_t) == 4`**) with ASan/UBSan.\n \n- **Note on other versions:** Any release/branch with the same stride arithmetic and row loop is likely affected on 32-bit.\n \n\n---\n\n## Root Cause (with code anchors)\n\n### Stride computation (writer)\n\n```c\nbytes_per_line = 4 * ((image->columns * bmp_info.bits_per_pixel + 31) / 32);\n```\n\n### Per-row base and 24-bpp loop (writer)\n\n```c\nq = pixels + ((ssize_t)image->rows - y - 1) * (ssize_t)bytes_per_line;\nfor (x = 0; x < (ssize_t)image->columns; x++) {\n *q++ = B(...); *q++ = G(...); *q++ = R(...); // writes 3 * width bytes\n}\n```\n\n### Allocation (writer)\n\n```c\npixel_info = AcquireVirtualMemory(image->rows,\n MagickMax(bytes_per_line, image->columns + 256UL) * sizeof(*pixels));\npixels = (unsigned char *) GetVirtualMemoryBlob(pixel_info);\n```\n\n### Dimension “caps” (insufficient)\n\nThe 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.\n\n---\n\n## Integer-Overflow Analysis (32-bit `size_t`)\n\nStride formula for 24-bpp:\n\n```\nbytes_per_line = 4 * ((width * 24 + 31) / 32)\n```\n\nThere are **two independent overflow hazards** on 32-bit:\n\n1. **Stage-1 multiply+add** in `(width * 24 + 31)` \n Overflow iff `width > ⌊(0xFFFFFFFF − 31) / 24⌋ = 178,956,969` \n → at **width ≥ 178,956,970** the numerator wraps small before `/32`, producing a **tiny** `bytes_per_line`.\n \n2. **Stage-2 final ×4** after the division \n Let `q = (width * 24 + 31) / 32`. Final `×4` overflows iff `q > 0x3FFFFFFF`. \n Solving gives **width ≥ 1,431,655,765 (0x55555555)**.\n \n\nBoth thresholds are **below** `INT_MAX` (≈2.147e9), so “int caps” don’t help.\n\n**Mismatch predicate (guaranteed OOB when overflowed):** \nPer-row write for 24-bpp is `row_bytes = 3*width`. Safety requires `row_bytes ≤ bytes_per_line`. \nUnder either overflow, `bytes_per_line` collapses → `3*width > bytes_per_line` holds → **OOB-write**.\n\n---\n\n## Concrete Demonstration\n\nChosen width: **`W = 178,957,200`** (just over Stage-1 bound)\n\n- Stage-1: `24*W + 31 = 4,294,972,831 ≡ 0x0000159F (mod 2^32)` → **5535**\n \n- Divide by 32: `5535 / 32 = 172`\n \n- Multiply by 4: `bytes_per_line = 172 * 4 = **688** bytes` ← tiny stride\n \n- Per-row data (24-bpp): `row_bytes = 3*W = **536,871,600** bytes`\n \n- Allocation used: `MagickMax(688, W+256) = **178,957,456** bytes`\n \n- **Immediate OOB**: first row writes ~536MB into a 178MB region, starting at a base advanced by only 688 bytes.\n \n---\n\n## Observed Result (ASan excerpt)\n\n```\nERROR: AddressSanitizer: heap-buffer-overflow on address 0x6eaac490\nWRITE of size 1 in WriteBMPImage coders/bmp.c:2309\n...\nallocated by:\n AcquireVirtualMemory MagickCore/memory.c:747\n WriteBMPImage coders/bmp.c:2092\n```\n\n- Binary: **ELF 32-bit i386**, Q8, non-HDRI\n \n- Resources set to permit execution of the writer path (defense-in-depth limits relaxed for repro)\n \n\n---\n\n## Exploitability & Risk\n\n- **Primitive:** Large, contiguous, attacker-controlled heap overwrite beginning at the scanline slot.\n \n- **Control:** Overwrite bytes are sourced from attacker-supplied pixels (e.g., crafted input image to be converted to BMP).\n \n- **Likely deployment:** Server-side, non-interactive conversion pipelines (UI:N).\n \n- **Outcome:** At minimum, deterministic crash (DoS). On many 32-bit allocators, well-understood heap shaping can escalate to **RCE**.\n \n\n**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.\n\n---\n\n## Reproduction (copy-paste triager script)\n\n**Test Environment:**\n\n- `docker run -it --rm --platform linux/386 debian:11 bash`\n \n- Install deps: `apt-get update && apt-get install -y build-essential git autoconf automake libtool pkg-config python3`\n \n- Clone & checkout: ImageMagick `7.1.2-0` → commit `3fcd081c0278427f...`\n \n- Configure 32-bit Q8 non-HDRI with ASan/UBSan (summary):\n\n```bash\n./configure \\\n --host=i686-pc-linux-gnu \\\n --build=x86_64-pc-linux-gnu \\\n --disable-dependency-tracking \\\n --disable-silent-rules \\\n --disable-shared \\\n --disable-openmp \\\n --disable-docs \\\n --without-x \\\n --without-perl \\\n --without-magick-plus-plus \\\n --without-lqr \\\n --without-zstd \\\n --without-tiff \\\n --with-quantum-depth=8 \\\n --disable-hdri \\\n CFLAGS=\"-O1 -g -fno-omit-frame-pointer -fsanitize=address,undefined\" \\\n CXXFLAGS=\"-O1 -g -fno-omit-frame-pointer -fsanitize=address,undefined\" \\\n LDFLAGS=\"-fsanitize=address,undefined\"\n\nmake -j\"$(nproc)\"\n```\n- Runtime limits to exercise writer:\n\n```bash\nexport MAGICK_WIDTH_LIMIT=200000000\nexport MAGICK_HEIGHT_LIMIT=200000000\nexport MAGICK_TEMPORARY_PATH=/tmp\nexport TMPDIR=/tmp\nexport ASAN_OPTIONS=\"detect_leaks=0:malloc_context_size=20:alloc_dealloc_mismatch=0\"\n```\n\n**One-liner trigger (no input file):**\n\n```bash\nW=178957200\n./utilities/magick \\\n -limit width 200000000 -limit height 200000000 \\\n -limit memory 268435456 -limit map 0 -limit disk 200000000000 \\\n -limit thread 1 \\\n -size ${W}x1 xc:black -type TrueColor -define bmp:format=bmp3 BMP3:/dev/null\n```\n\n**Expected:** ASan heap-buffer-overflow in `WriteBMPImage` (will be provided in a private gist link).\n\n**Alternate PoC (raw PPM generator):**\n\n```python\n#!/usr/bin/env python3\nW, H, MAXV = 180_000_000, 1, 255 \n# W > 178,956,969\nwith open(\"huge.ppm\", \"wb\") as f:\n f.write(f\"P6\\n{W} {H}\\n{MAXV}\\n\".encode(\"ascii\"))\n chunk = (b\"\\x41\\x42\\x43\") * (1024*1024)\n remaining = 3 * W\n while remaining:\n n = min(remaining, len(chunk))\n f.write(chunk[:n]); remaining -= n\n# Then: magick huge.ppm out.bmp\n```\n\n---\n\n## Proposed Severity\n\n- **Primary vector (server auto-convert):** `AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H` → **9.8 Critical**\n \n- **If strictly CLI/manual conversion:** `UI:R` → **8.8 High**\n \n\n---\n\n## Maintainer Pushbacks — Pre-empted\n\n- **“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.\n \n- **“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.\n \n- **“Resource policy blocks large images.”** That’s environment-dependent defense-in-depth; arithmetic must be correct.\n \n---\n\n## Remediation (Summary)\n\nAdd 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.\n\nConcretely:\n\n- Validate width and bits_per_pixel before the stride formula to ensure (width*bpp + 31) cannot overflow a size_t.\n- Compute row_bytes for the chosen bpp and assert row_bytes <= bytes_per_line.\n- Bound rows * stride before allocating and ensure biSizeImage (DIB 32-bit) cannot overflow.\n\nA full suggested guarded implementation is provided in Appendix A — Full patch (for maintainers).\n\n---\n\n## Regression Tests to Include (PR-friendly)\n\n1. **32-bit overflow repros** (with ASan):\n \n - `rows=1`, `width ≥ 178,956,970`, `bpp=24` → now cleanly errors.\n \n - `rows=2`, same bound → no row overlap; clean error.\n \n2. **64-bit sanity:** Medium images (e.g., `8192×4096`, 24-bpp) round-trip; header’s `biSizeImage = rows * bytes_per_line`.\n \n3. **Packed bpp (1/4/8):** Validate `row_bytes = (width*bpp+7)/8` (guarded), 4-pad, and **payload ≤ stride** holds.\n\n---\n\n## Attachments (private BMP_Package) \nProvided with report: README.md, poc_ppm_generator.py, repro_commands.sh, full_asan_bmp_crash.txt, appendix_a_patch_block.c.

`4*((W*bpp+31)/32)`). \n \n- It **fixes the header** (`biSizeImage`) to be a checked product, instead of a potentially wrapped multiplication. \n \n- It **guards allocation** where you presently allocate `rows × MagickMax(bytes_per_line, columns+256)`. \n \n- 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. \n \n\n---\n\n## Notes\n\n- **Behavior preserved**: The stride value for normal images is unchanged; only pathological integer states are rejected. \n \n- **Header consistency**: `biSizeImage = rows * bytes_per_line` remains true by construction, but now cannot overflow a 32-bit DIB field. \n \n- **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.\n \n\nA 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.\n\n\n\n### Appendix B — Arithmetic Worked Example (W=178,957,200)\n\n- `(24W + 31) mod 2^32 = 5535`\n \n- `bytes_per_line = 4 * (5535/32) = 688`\n \n- `row_bytes (24-bpp) = 536,871,600`\n \n- Allocation via

Lumina Mescuwa \n**Product:** ImageMagick 7 (MagickCore) \n**Component:** `MagickCore/blob.c` (Blob I/O - BlobStream) \n**Tested:** 7.1.2-0 (source tag) and 7.1.2-1 (Homebrew), macOS arm64, clang-17, Q16-HDRI \n**Impact:** Heap out-of-bounds **WRITE** (attacker-controlled bytes at attacker-chosen offset) → memory corruption; potential code execution \n\n---\n\n## Executive Summary\n\nFor 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.\n\n---\n\n## Affected Scope\n\n- **Versions confirmed:** 7.1.2-0, 7.1.2-1\n \n- **Architectures:** Observed on macOS arm64; architecture-agnostic on LP64\n \n- 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)).\n \n- **Not required:** External delegates; special policies; integer wraparound\n \n\n---\n\n## Technical Root Cause\n\n**Types (LP64):** \n`offset: MagickOffsetType` (signed 64-bit) \n`extent/length/quantum: size_t` (unsigned 64-bit) \n`data: unsigned char*`\n\n**Contract mismatch:**\n\n- [`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.\n \n- [`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:\n \n ```\n q = data + (size_t)offset;\n memmove(q, src, length);\n ```\n \n There is **no guarantee** that `extent ≥ offset + length` post-growth. With `offset ≫ extent`, `q` is beyond the allocation.\n \n\n**Wrap-free demonstration:** \nInitialize `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.\n\n---\n\n## Exploitability & Reachability\n\n- **Primitive:** Controlled bytes written at a controlled displacement from the buffer base.\n \n- **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.\n \n- **Determinism:** Once a forward seek past end occurs, the first subsequent write reliably corrupts memory.\n \n\n---\n\n## Impact Assessment\n\n- **Integrity:** High - adjacent object/metadata overwrite plausible.\n \n- **Availability:** High - reliably crashable (ASan and non-ASan).\n \n- **Confidentiality:** High - Successful exploitation to RCE allows the attacker to read all data accessible by the compromised process.\n \n- **RCE plausibility:** Typical of heap OOB writes in long-lived image services; allocator/layout dependent.\n \n\n---\n\n## CVSS v3.1 Rationale (9.8)\n\n- **AV:N / PR:N / UI:N** - server-side image processing is commonly network-reachable without auth or user action.\n \n- **AC:L** - a single forward seek + write suffices; no races or specialized state.\n \n- **S:U** - corruption localized to the ImageMagick process.\n \n- **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).\n \n\n_Base scoring assumes successful exploitation; environmental mitigations are out of scope of Base metrics._\n\n---\n\n## Violated Invariant\n\n> **Before copying `length` bytes at `offset`, enforce `extent ≥ offset + length` with overflow-checked arithmetic.**\n\nThe BlobStream growth policy preserves amortized efficiency but fails to enforce this **per-write** safety invariant.\n\n---\n\n## Remediation (Principle)\n\nIn [`WriteBlob()`](https://github.com/ImageMagick/ImageMagick/blob/3fcd081c0278427fc0e8ac40ef75c0a1537792f7/MagickCore/blob.c#L5915-L5938) (BlobStream case):\n\n1. **Checked requirement:** \n `need = (size_t)offset + length;` → if `need < (size_t)offset`, overflow → fail.\n \n2. **Ensure capacity ≥ need:** \n `target = MagickMax(extent + quantum + length, need);` \n (Optionally loop, doubling `quantum`, until `extent ≥ need` to preserve amortization.)\n \n3. **Reallocate to `target + 1` before copying;** then perform the move.\n \n\n**Companion hardening (recommended):**\n\n- 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.\n \n- Centralize blob arithmetic in checked helpers.\n \n- Unit tests: forward-seek-then-write (success and overflow-reject).\n \n\n---\n\n## Regression & Compatibility\n\n- **Behavior change:** Forward-seeked writes will either allocate to required size or fail cleanly (overflow/alloc-fail).\n \n- **Memory profile:** Single writes after very large seeks may allocate large buffers; callers requiring sparse behavior should use file-backed streams.\n \n\n---\n\n## Vendor Verification Checklist\n\n- Reproduce with a minimal in-memory BlobStream harness under ASan.\n \n- Apply fix; verify `extent ≥ offset + length` at all write sites.\n \n- Add forward-seek test cases (positive/negative).\n \n- Audit other growth sites (`SetBlobExtent`, stream helpers).\n \n- Clarify BlobStream seek semantics in documentation.\n \n- Unit test: forward seek to large offset on **BlobStream** followed by 1–8 byte writes; assert either growth to `need` or clean failure.\n \n\n---\n\n# PoC / Reproduction / Notes\n\n## Environment\n\n- **OS/Arch:** macOS 14 (arm64)\n \n- **Compiler:** clang-17 with AddressSanitizer\n \n-

arbitrary code execution\n## Summary\nA 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.\n<br>\n\n## Details\n### root cause\n```\nMagickExport size_t InterpretImageFilename(const ImageInfo *image_info,\n Image *image,const char *format,int value,char *filename,\n ExceptionInfo *exception)\n{\n\n...\n\n while ((cursor=strchr(cursor,'%')) != (const char *) NULL)\n {\n const char\n *q = cursor;\n\n ssize_t\n offset = (ssize_t) (cursor-format);\n\n cursor++; /* move past '%' */\n if (*cursor == '%')\n {\n /*\n Escaped %%.\n */\n cursor++;\n continue;\n }\n /*\n Skip padding digits like %03d.\n */\n if (isdigit((int) ((unsigned char) *cursor)) != 0)\n (void) strtol(cursor,(char **) &cursor,10);\n switch (*cursor)\n {\n case 'd':\n case 'o':\n case 'x':\n {\n ssize_t\n count;\n\n count=FormatLocaleString(pattern,sizeof(pattern),q,value);\n if ((count <= 0) || (count >= MagickPathExtent) ||\n ((offset+count) >= MagickPathExtent))\n return(0);\n (void) CopyMagickString(p+offset,pattern,(size_t) (MagickPathExtent-\n offset));\n cursor++;\n break;\n }\n```\nWhen 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.\n<br>\n```\nMagickExport ssize_t FormatLocaleString(char *magick_restrict string,\n const size_t length,const char *magick_restrict format,...)\n{\n ssize_t\n n;\n\n va_list\n operands;\n\n va_start(operands,format);\n n=FormatLocaleStringList(string,length,format,operands);\n va_end(operands);\n return(n);\n}\n```\n```\nMagickPrivate ssize_t FormatLocaleStringList(char *magick_restrict string,\n const size_t length,const char *magick_restrict format,va_list operands)\n{\n...\nn=(ssize_t) _vsnprintf_l(string,length,format,locale,operands);\n```\nInside 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.\n<br>\n## PoC\n### 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.\n<br>\n\n**Exploitation Process:**\n1. Format string payload corrupts stack pointers through positional parameters\n2. Multiple 2-byte writes (%hn) progressively overwrite the return address \n3. Final payload redirects execution to a one-gadget (0x00007ffff66ebc85)\n4. One-gadget executes `/bin/sh` with inherited process permissions\n<br>\n\n**Remote Exploitation Feasibility:**\nWhile 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.\n<br>\n\n**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.\n\n**Note:** This demonstrates complete system compromise, as the attacker gains interactive shell access to the target system.\n<br>\n\n## Impact\nThis 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.\n\nThe 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.\n<br>\n\n## Suggested Fix\n\nTwo potential mitigation approaches:\n\n1. **Input Validation**: Add format string validation in `InterpretImageFilename` to reject filenames containing format specifiers (`%n`, `%s`, `%x`, etc.) before passing to `FormatLocaleString`\n2. **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`\n<br>\n\n## Credits\n### Team Daemon Fuzz Hunters\n**Bug Hunting Master Program, HSpace/Findthegap**\n<br>\n\n**Woojin Park**\n@jin-156\n[1203kids@gmail.com](mailto:1203kids@gmail.com)\n\n**Hojun Lee**\n@leehohojune \n[leehojune@korea.ac.kr](mailto:leehojune@korea.ac.kr)\n\n**Youngin Won**\n@amethyst0225\n[youngin04@korea.ac.kr](mailto:youngin04@korea.ac.kr)\n\n**Siyeon Han**\n@hanbunny\n[kokosyeon@gmail.com](mailto:kokosyeon@gmail.com)\n\n# Additional notes from the ImageMagick team:\n\nOn 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:\n\nTo prevent unintended interpretation of the filename as a format string, users can explicitly disable format string parsing by defining the filename as a literal.

-geometry \":\" leads to crash\n## Summary\nPassing 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.\n\n## Details\n**Root Cause**\n1. `montage -geometry \":\" ...` reaches `MagickCore/geometry.c:GetGeometry().`\n2. `StringToDouble/InterpretLocaleValue` parses `\":\"` as `0.0;` then: \nhttps://github.com/ImageMagick/ImageMagick/blob/0ba1b587be17543b664f7ad538e9e51e0da59d17/MagickCore/geometry.c#L355\n`WidthValue` (and/or `HeightValue)` is set with a zero dimension.\n3. In MagickCore/resize.c:ThumbnailImage(), the code computes:\nhttps://github.com/ImageMagick/ImageMagick/blob/0ba1b587be17543b664f7ad538e9e51e0da59d17/MagickCore/resize.c#L4625-L4629\ncausing a division by zero and immediate crash.\n\nThe issue is trivially triggerable without external input files (e.g., using `xc:white`).\n\n### Reproduction\nEnvironment\n```\nVersion: ImageMagick 7.1.2-1 (Beta) Q16-HDRI x86_64 0ba1b587b:20250812 https://imagemagick.org\nFeatures: Cipher DPC HDRI\nDelegates (built-in): bzlib fontconfig freetype jbig jng jpeg lcms lzma pangocairo png tiff x xml zlib\nCompiler: clang (14.0.0)\nOS/Arch: Linux x86_64\n```\nSteps\n```\n./bin/magick montage -geometry : xc:white null:\n```\nObserved result\n```\nIOT instruction (core dumped)\n# (Environment-dependent: SIGFPE/abort may be observed.)\n```\n\n## PoC\nNo external file required; the pseudo image xc:white suffices:\n```\n./bin/magick montage -geometry : xc:white null:\n```\n\n## Impact\n- **Denial of Service:** A divide-by-zero in `ThumbnailImage()` causes immediate abnormal termination (e.g., SIGFPE/abort), crashing the ImageMagick process.\n\n\n## Suggested fix\nDefensively reject zero dimensions early in `ThumbnailImage()`:\n```c\nif ((columns == 0) || (rows == 0)) {\n (void) ThrowMagickException(exception, GetMagickModule(), OptionError,\n \"InvalidGeometry\", \"thumbnail requires non-zero dimensions: %.20gx%.20g\",\n (double) columns, (double) rows);\n return (Image *) NULL;\n}\n```\nAdditionally, 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).\n\n## Credits\n### Team Daemon Fuzz Hunters\n**Bug Hunting Master Program,
