Linux Distros Unpatched Vulnerability : CVE-2026-105403

medium Nessus Plugin ID 364308

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- ImageMagick before 6.9.13-56 and 7.x before 7.1.2-31 allows a security policy bypass when a policy uses coder, rather than module, as its domain. An attacker can supply a crafted image to evade coder-based policy restrictions, causing ImageMagick to process formats the administrator intended to block.
(CVE-2026-105403)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
