ImageMagick < 6.9.13-58 / 7.x < 7.1.2-33 Heap Buffer Underwrite (CVE-2026-109964)

medium Nessus Plugin ID 378781

Synopsis

The remote host has an application installed that is affected by a heap buffer underwrite vulnerability.

Description

The remote host has a version of ImageMagick installed that is prior to 6.9.13-58, or 7.x prior to 7.1.2-33. It is, therefore, affected by a heap buffer underwrite vulnerability:

 - ImageMagick before 7.1.2-33 and 6.9.13-58 contains a heap buffer underwrite vulnerability in DecodeImage() in coders/pict.c on 32-bit builds due to pointer arithmetic overflow. Attackers can supply a crafted PICT file with maximized row, column and bytes-per-line values to bypass bounds checks and write up to 128 controlled bytes below the heap buffer, causing crashes or code execution. (CVE-2026-109964)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number. The detections used by this plugin do not determine the architecture of the installed build, so the plugin reports only when the scan is configured to show potential false alarms.

Solution

Upgrade to ImageMagick version 6.9.13-58 / 7.1.2-33 or later.
