ImageMagick < 6.9.13-40 / 7.x < 7.1.2-15 Vulnerability

medium Nessus Plugin ID 362653

Synopsis

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

Description

The remote host has a version of ImageMagick installed that is prior to 6.9.13-40, or 7.x prior to 7.1.2-15. It is, therefore, affected by a vulnerability.

 - ImageMagick before 7.1.2-15 and before 6.9.13-40 contains a heap-buffer-overflow read vulnerability in GetPixelIndex caused by OpenPixelCache updating image channel metadata before pixel cache memory allocation. Attackers can trigger memory and disk allocation failures to cause a heap-buffer-overflow read affecting any writer calling GetPixelIndex. (CVE-2026-56362)

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 6.9.13-40 / 7.1.2-15 or later.
