How to fix?

Upgrade Alpine:3.20 buildah to version 1.37.4-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream buildah package and not the buildah package as distributed by Alpine. See How to fix? for Alpine:3.20 relevant fixed versions and status.

A flaw was found in Go. When FIPS mode is enabled on a system, container runtimes may incorrectly handle certain file paths due to improper validation in the containers/common Go library. This flaw allows an attacker to exploit symbolic links and trick the system into mounting sensitive host directories inside a container. This issue also allows attackers to access critical host files, bypassing the intended isolation between containers and the host system.
