ImageMagick is free and open-source software used for editing and manipulating digital images. ImageMagick versions lower than 14.8.2 include insecure functions: SeekBlob(), which permits advancing the stream offset beyond the current end without increasing capacity, and WriteBlob(), which 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. This is fixed in version 14.8.2.

The remote Debian 12 / 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5997 advisory.

    Multiple memory corruption vulnerbilities were discovered in imagemagick,     a software suit used for editing and manipulating digital images, which     could lead to information leak, denial of service, and potentially arbitrary     code execution.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 6.9.11.60+dfsg-1.6+deb12u4.

    For the stable distribution (trixie), these problems have been fixed in     version 8:7.1.1.43+dfsg1-1+deb13u2.

    We recommend that you upgrade your imagemagick packages.

    Multiple vulnerabilities were fixed in imagemagick an image manipulation     software suite.

    CVE-2025-53014

        A heap buffer overflow was found in the `InterpretImageFilename`         function. The issue stems from an off-by-one error that causes         out-of-bounds memory access when processing format strings         containing consecutive percent signs (`%%`).

    CVE-2025-53019

        ImageMagick's `magick stream` command, specifying multiple         consecutive `%d` format specifiers in a filename template         caused a memory leak

    CVE-2025-53101

        ImageMagick's `magick mogrify` command, specifying         multiple consecutive `%d` format specifiers in a filename         template caused internal pointer arithmetic to generate         an address below the beginning of the stack buffer,         resulting in a stack overflow through `vsnprintf()`.

    CVE-2025-55154

        The magnified size calculations in ReadOneMNGIMage         (in coders/png.c) are unsafe and can overflow,         leading to memory corruption.

    CVE-2025-55212

        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)

    CVE-2025-55298

        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.

    CVE-2025-57803

        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.

    CVE-2025-57807

        A security problem was found in SeekBlob(), which permits         advancing the stream offset beyond the current end without         increasing capacity, and WriteBlob(), which 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 2??         arithmetic wrap, external delegates, or policy settings         are required.

    For Debian 11 bullseye, these problems have been fixed in version     8:6.9.11.60+dfsg-1.3+deb11u6.

    We recommend that you upgrade your imagemagick packages.
