"The remote host has a version of ImageMagick installed that is prior to 6.9.13-48 or 7.x prior to 7.1.2-24. It is,
therefore, affected by multiple vulnerabilities:

  - A missing check in the DCM decoder could result in an image with invalid dimensions that may trigger crashes
    during subsequent operations. (CVE-2026-49218)

  - A missing check of a return value could lead to a heap buffer over-write in the MAT decoder on 32-bit systems.
    (CVE-2026-48994)

  - Incorrect filename parsing with symlinks allows attackers to bypass security policies and access restricted files.
    (CVE-2026-49219)

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