Red Hat Security Advisory 2011-1694-03 - 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 manual page. With this update, the capsh manual page is included.

Red Hat Security Advisory 2011-1691-03 - The util-linux-ng packages contain a large variety of low-level system utilities that are necessary for a Linux operating system to function. Multiple flaws were found in the way the mount and umount commands performed mtab file updates. A local, unprivileged user allowed to mount or unmount file systems could use these flaws to corrupt the mtab file and create a stale lock file, preventing other users from mounting and unmounting file systems.
