ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-51 and 7.1.2-26, when identifying an image with a crafted 8BIM profile with a specific format string a use-after-free will occur. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to
    versions 6.9.13-51 and 7.1.2-26, when identifying an image with a crafted 8BIM profile with a specific
    format string a use-after-free will occur. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26.
    (CVE-2026-55510)

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1790182513 advisory.

  - ImageMagick is free and open-source software used for editing and manipulating digital images. Versions     prior to 7.1.2-0 and 6.9.13-26 have a heap buffer overflow 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 (`%%`). Versions 7.1.2-0 and 6.9.13-26 fix the issue.
    (CVE-2025-53014)

  - ImageMagick is free and open-source software used for editing and manipulating digital images. In versions     prior to 7.1.2-0 and 6.9.13-26, in ImageMagick's `magick stream` command, specifying multiple consecutive     `%d` format specifiers in a filename template causes a memory leak. Versions 7.1.2-0 and 6.9.13-26 fix the     issue. (CVE-2025-53019)

  - ImageMagick is free and open-source software used for editing and manipulating digital images. In versions     prior to 7.1.2-0 and 6.9.13-26, 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()`. Versions     7.1.2-0 and 6.9.13-26 fix the issue. (CVE-2025-53101)

  - ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 6.9.13-27 and 7.1.2-1, there is undefined behavior (function-type-mismatch) in splay tree cloning     callback. This results in a deterministic abort under UBSan (DoS in sanitizer builds), with no crash in a     non-sanitized build. This issue has been patched in versions 6.9.13-27 and 7.1.2-1. (CVE-2025-55160)

  - ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to     versions 6.9.13-28 and 7.1.2-2, 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. This issue has been     patched in versions 6.9.13-28 and 7.1.2-2. (CVE-2025-55212)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
