ImageMagick < 6.9.13-48 / 7.x < 7.1.2-23 Multiple Vulnerabilities

medium Nessus Plugin ID 317747

Language:

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 6.9.13-47 or 7.x prior to 7.1.2-22. It is, therefore, affected by multiple vulnerabilities:

 — An attacker who can connect to a magick -distribute-cache service can hijack a file descriptor in the server process when a race condition is met. (CVE-2026-46693)

 — The distributed pixel cache was originally designed to operate without a challenge–response authentication model. However, given today’s heightened security expectations, we have changed our implementation.
 (CVE-2026-47165)

 — An attacker who can connect to a magick -distribute-cache service can cause a heap buffer over-read in the server process. (CVE-2026-47166)

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 / 7.1.2-23 or later.
