AI-suggested

Red Hat has released updated policycoreutils RPMs (version 3.11-2.2.hum1) that fix this vulnerability. Users should apply these security updates promptly. Until the update is applied, a recommended workaround is to avoid using 'fixfiles relabel' or 'fixfiles restore' commands and instead use 'restorecon -R /' for filesystem relabeling operations.

Description

A TOCTOU race condition vulnerability exists in the fixfiles script of policycoreutils in Red Hat Hardened Images. This flaw allows a local attacker to exploit a timing window during filesystem relabeling to manipulate SELinux labels on arbitrary system files, potentially undermining SELinux protections on critical files such as /etc/shadow. The vulnerability requires local access, winning a race condition, and an administrator running fixfiles relabel or fixfiles restore. A workaround is to use 'restorecon -R /' instead of the vulnerable fixfiles commands. An official fix has been released in updated policycoreutils RPMs.
