ImageMagick < 6.9.13-34 / 7.x < 7.1.2-9 Use-After-Free / Double-Free (GHSA-q3hc-j9x5-mp9m)

medium Nessus Plugin ID 277548

Synopsis

The remote host has an application installed that is affected by use-after-free and double-free vulnerabilities.

Description

The remote host has a version of ImageMagick installed that is prior to 6.9.13-34 or 7.1.2-9. It is, therefore, affected by use-after-free and double-free vulnerabilities as referenced in the GHSA-q3hc-j9x5-mp9m 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)

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

Solution

Upgrade to ImageMagick version 7.1.2-9 or later.
