Updated libxml2 packages that fix one security issue are now available for
Red Hat Enterprise Linux 7.

Red Hat Product Security 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.

It was discovered that libxml2 loaded external parameter entities even when
entity substitution was disabled. A remote attacker able to provide a
specially crafted XML file to an application linked against libxml2 could
use this flaw to conduct XML External Entity (XXE) attacks, possibly
resulting in a denial of service or an information leak on the system.

The CVE-2014-0191 issue was discovered by Daniel P. Berrange of Red Hat.

All libxml2 users 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.
