1. Summary:

Updated util-linux-ng packages that fix one security issue, several bugs,
and add various enhancements 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64

3. Description:

The util-linux-ng packages contain a large variety of low-level system
utilities that are necessary for a Linux operating system to function.

An information disclosure flaw was found in the way the mount command
reported errors. A local attacker could use this flaw to determine the
existence of files and directories they do not have access to.
(CVE-2013-0157)

These updated util-linux-ng packages include numerous bug fixes and
enhancements. Space precludes documenting all of these changes in this
advisory. Users are directed to the Red Hat Enterprise Linux 6.4 Technical
Notes, linked to in the References, for information on the most significant
of these changes.

All users of util-linux-ng are advised to upgrade to these updated
packages, which contain backported patches to correct these issues and add
these enhancements.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
