Description

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The libcap packages provide a library and tools for getting and setting POSIX capabilities.

It was found that capsh did not change into the new root when using the '--chroot' option. An application started via the 'capsh --chroot' command could use this flaw to escape the chroot restrictions.
