How to fix?

Upgrade Alpine:3.15 cups to version 2.3.3-r7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cups package and not the cups package as distributed by Alpine. See How to fix? for Alpine:3.15 relevant fixed versions and status.

OpenPrinting CUPS is an open source printing system. In versions 2.4.2 and prior, a heap buffer overflow vulnerability would allow a remote attacker to launch a denial of service (DoS) attack. A buffer overflow vulnerability in the function format_log_line could allow remote attackers to cause a DoS on the affected system. Exploitation of the vulnerability can be triggered when the configuration file cupsd.conf sets the value of loglevel to DEBUG. No known patches or workarounds exist at time of publication.
