Amazon Linux 2 : cups, --advisory ALAS2-2025-3012 (ALAS-2025-3012)

medium Nessus Plugin ID 266159

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of cups installed on the remote host is prior to 1.6.3-51. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-3012 advisory.

 OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, an unsafe deserialization and validation of printer attributes causes null dereference in the libcups library. This is a remote DoS vulnerability available in local subnet in default configurations. It can cause the cups & cups-browsed to crash, on all the machines in local network who are listening for printers (so by default for all regular linux machines). On systems where the vulnerability CVE-2024-47176 (cups-filters 1.x/cups-browsed 2.x vulnerability) was not fixed, and the firewall on the machine does not reject incoming communication to IPP port, and the machine is set to be available to public internet, attack vector Network is possible. The current versions of CUPS and cups- browsed projects have the attack vector Adjacent in their default configurations. Version 2.4.13 contains a patch for CVE-2025-58364. (CVE-2025-58364)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update cups' or or 'yum update --advisory ALAS2-2025-3012' to update your system.
