Description

Jon Erickson of iSIGHT Partners Labs discovered a heap overflow in xml-security-c, an implementation of the XML Digital Security specification. The fix to address CVE-2013-2154

introduced the possibility of a heap overflow in the processing of malformed XPointer expressions in the XML Signature Reference processing code, possibly leading to arbitrary code execution.
