Synopsis :

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

Description :

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
moderate 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 denial of service flaw was found in the way libxml2 performed string
substitutions when entity values for entity references replacement was
enabled. A remote attacker could provide a specially crafted XML file
that, when processed by an application linked against libxml2, would
lead to excessive CPU consumption. (CVE-2013-0338)

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.
