Updated libxml2 packages that fix one security issue are now available for
Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
important 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 libxml2 library is a development toolbox providing the implementation
of various XML standards.

A heap-based buffer underflow flaw was found in the way libxml2 decoded
certain entities. A remote attacker could provide a specially-crafted XML
file that, when opened in an application linked against libxml2, would
cause the application to crash or, potentially, execute arbitrary code with
the privileges of the user running the application. (CVE-2012-5134)

All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. The desktop must be
restarted (log out, then log back in) for this update to take effect.
