REDHAT-BUG-2315691
First published: Mon Sep 30 2024(Updated: )
A flaw in the containers/common Go library, used by container runtimes such as Podman, Buildah, and CRI-O, allows a malicious container image to exploit the FIPS mode to bind mount arbitrary host directories into the container. The flaw arises from the MountsWithUIDGID() function, which attempts to mount a FIPS-related directory inside the container but does not properly verify the path. If the FIPS path is a symlink, it could point to arbitrary directories on the host, allowing an attacker to access sensitive host files.
