Summary Exiv2 Segmentation Faults in Exiv2::EpsImage::writeMetadata() via crafted EPS file ### Impact An out-of-bounds read was found in Exiv2 versions v0.28.5 and earlier. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The out-of-bounds read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as delete. ### Patches The bug is fixed in version v0.28.6. ### Credit Thank you to @dragonArthurX for reporting this issue. ### Details (from original report by @dragonArthurX ) **Version:** Tested on v0.28.5 (latest official release) Commit: 907169fa643c2c74c14fd4106e55eaeee3634d9f **Platform:** Ubuntu 20.04.6 LTS (x86_64) **Build Steps:** ```bash git clone https://github.com/Exiv2/exiv2.git cd exiv2 git checkout v0.28.5 mkdir build-v0.28.5 && cd build-v0.28.5 cmake -DCMAKE_C_COMPILER=/fuzzer/afl-clang-fast -DCMAKE_CXX_COMPILER=/fuzzer/afl-clang-fast++ -DCMAKE_C_FLAGS="-g -fsanitize=address" -DCMAKE_CXX_FLAGS="-g -fsanitize=address" -DBUILD_SHARED_LIBS=OFF ../ ``` **Command line to reproduce:** ```bash /home/exiv2/build/bin/exiv2 -d a -f /home/poc ``` **Crash Output:** ``` AddressSanitizer:DEADLYSIGNAL ================================================================ = ==376531==ERROR: AddressSanitizer: SEGV on unknown address 0x7fd92236b0e7 (pc 0x7fd82314dcd2 bp 0x7ffd540ceba0 sp 0x7ffd540ce358 T0) ==376531==The signal is caused by a READ memory access. #0 0x7fd82314dcd2 /build/glibc-B3wQXB/glibc-2.31/string/../sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S:383 #1 0x4ed131 in __asan_memcpy (/home/exiv2/build-v0.28.5/bin/exiv2+0x4ed131) #2 0x6184b1 in Exiv2::MemIo::write(unsigned char const*, unsigned long) /home/exiv2/src/basicio.cpp:704:5 #3 0xad336d in (anonymous namespace)::writeTemp(Exiv2::BasicIo&, unsigned char const*, unsigned long) /home/exiv2/src/epsimage.cpp:90:14 #4 0xac3a07 in (anonymous namespace)::readWriteEpsMetadata(Exiv2::BasicIo&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&, std::vector<Exiv2::NativePreview, std::allocator<Exiv2::NativePreview> >&, bool) /home/exiv2/src/epsimage.cpp:1009:7 #5 0xad1175 in Exiv2::EpsImage::writeMetadata() /home/exiv2/src/epsimage.cpp:1103:3 #6 0x5d2383 in Action::Erase::run(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) /home/exiv2/app/actions.cpp:713:14 #7 0x522d02 in main /home/exiv2/app/exiv2.cpp:177:25 #8 0x7fd8230b6082 in __libc_start_main /build/glibc-B3wQXB/glibc-2.31/csu/../csu/libc-start.c:308:16 #9 0x4714dd in _start (/home/exiv2/build-v0.28.5/bin/exiv2+0x4714dd) AddressSanitizer can not provide additional info.
