Description


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.
(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.
