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.
(CVE-2014-0191)

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.
