Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: cups (UTSA-2025-987463)

high Nessus Plugin ID 268281

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-987463 advisory.

OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, when the `AuthType` is set to anything but `Basic`, if the request contains an `Authorization: Basic ...` header, the password is not checked. This results in authentication bypass.
Any configuration that allows an `AuthType` that is not `Basic` is affected. Version 2.4.13 fixes the issue.

Tenable has extracted the preceding description block directly from the Unity Linux 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 cups package.
