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 attacks, possibly resulting in a denial of service or an information leak on the system. An out-of-bounds read flaw was found in the way libxml2 detected the end of an XML file. A remote attacker could provide a specially crafted XML file that, when processed by an application linked against libxml2, could cause the application to crash. 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 backported patches to correct these issues. The desktop must be restarted for this update to take effect.
