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)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. (CVE-2013-2877)
