Linux Distros Unpatched Vulnerability : CVE-2026-64612

high Nessus Plugin ID 328148

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.

 - A flaw was found in libcupsfilters and cups-filters. The PNG image reading function creates a libpng reader without installing an error recovery handler, causing the CUPS image filter process to abort when processing a malformed PNG file. An unauthenticated attacker could exploit this by submitting a specially crafted PNG print job, leading to denial of service of the in-flight print job. (CVE-2026-64612)

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

Solution

There is no known solution at this time.
