Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated libcap packages that fix one security issue and one bug are
now available for Red Hat Enterprise Linux 6.

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.

This update also fixes the following bug :

* Previously, the libcap packages did not contain the capsh(1) manual
page. With this update, the capsh(1) manual page is included.

All libcap users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues.
