"The version of ImageMagick installed on the remote host is prior to 6.9.10.97-1. It is, therefore, affected by a
vulnerability as referenced in the ALAS2-2025-3096 advisory.

    ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to
    7.1.2-9 and 6.9.13-34, there is a vulnerability in ImageMagick's Magick++ layer that manifests when
    Options::fontFamily is invoked with an empty string. Clearing a font family calls RelinquishMagickMemory
    on _drawInfo->font, freeing the font string but leaving _drawInfo->font pointing to freed memory while
    _drawInfo->family is set to that (now-invalid) pointer. Any later cleanup or reuse of _drawInfo->font re-
    frees or dereferences dangling memory. DestroyDrawInfo and other setters (Options::font, Image::font)
    assume _drawInfo->font remains valid, so destruction or subsequent updates trigger crashes or heap
    corruption. This vulnerability is fixed in 7.1.2-9 and 6.9.13-34. (CVE-2025-65955)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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