Ubuntu 22.04 LTS / 24.04 LTS / 25.04 / 25.10 : CUPS vulnerability (USN-7912-1)

medium Nessus Plugin ID 277582

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 / 25.10 host has packages installed that are affected by a vulnerability as referenced in the USN-7912-1 advisory.

 Johannes Meixner and Paul Zirnik discovered that CUPS incorrectly handled clients that send messages slowly. A remote attacker could possibly use this issue to cause CUPS to stop responding, resulting in a denial of service. (CVE-2025-58436)

 In addition, this update fixes a regression introduced in USN-7897-1 which resulted in certain invalid configuration file directives to cause the CUPS daemon to fail to start.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
