Rocky Linux 9.6 [TuxCare] Security Update: ImageMagick / ImageMagick-c++ / ImageMagick-c++-devel / etc Multiple Vulnerabilities (ALMALINUX9.6:CLSA-2026:1786695462)

medium Nessus Plugin ID 351879

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1786695462 advisory.

- ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-1, when preparing to transform from Log to sRGB colorspaces, the logmap construction fails to handle cases where the reference-black or reference-white value is larger than 1024. This leads to corrupting memory beyond the end of the allocated logmap buffer. This issue has been patched in version 7.1.2-1. (CVE-2025-55005)

- ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-26, an incorrect handling of arguments can cause a heap buffer over-write in the JP2 encoder. This issue has been fixed in version7.1.2-26. (CVE-2026-55597)

- ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-27, the BGR decoder does not check for an end-of-file in every location so a crafted image could result in an heap buffer over-read. This issue has been fixed in version 7.1.2-27. (CVE-2026-64685)

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

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.6:CLSA-2026:1786695462.
