Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: ImageMagick (UTSA-2026-007076)

high Nessus Plugin ID 305923

Synopsis

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

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007076 advisory.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a stack buffer overflow exists in ImageMagick's morphology kernel parsing functions. User-controlled kernel strings exceeding a buffer are copied into fixed-size stack buffers via memcpy without bounds checking, resulting in stack corruption. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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

Solution

Update the affected ImageMagick package.
