ImageMagick < 6.9.13-48 / 7.x < 7.1.2-24 Multiple Vulnerabilities

high Nessus Plugin ID 321441

Synopsis

The remote host has an application installed that is affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade to ImageMagick version 6.9.13-48 / 7.1.2-24 or later.
