ImageMagick < 6.9.13-56 / 7.x < 7.1.2-31 Multiple Vulnerabilities

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 6.9.13-56, or 7.x prior to 7.1.2-31. It is, therefore, affected by multiple vulnerabilities:

- ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a NULL pointer dereference in the PNM coder. When the coder reaches a memory (resource) limit at a specific point during processing, the failed allocation is not handled and a NULL pointer is dereferenced, which can lead to a denial of service (application crash) when processing a specially crafted or sufficiently large PNM image. (CVE-2026-93588)

- ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a use-after-free vulnerability in the ImagesToBlob method, caused by a pointer that is not updated correctly. Exploitation may result in a limited availability impact (e.g., a crash of the affected process). (CVE-2026-93586)

- ImageMagick before 7.1.2-31 and 6.9.13-56 contains a division-by-zero flaw in the FLIF encoder. An incorrect value for ticks per second in the image being encoded causes a divide-by-zero and crashes the encoder, resulting in a denial of service. (CVE-2026-93589)

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 6.9.13-56 / 7.1.2-31 or later.
