xml-security-c - heap overflow

Jon Erickson of iSIGHT Partners Labs discovered a heap overflow in
xml-security-c, an implementation of the XML Digital Security

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.
