Synopsis: Low: libcap security and bug fix update
Issue Date: 2011-12-06
CVE Numbers: CVE-2011-4099

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. (CVE-2011-4099)

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.
