Details

Juri Aedla discovered that libxml2 contained an off by one error in its
XPointer functionality. If a user or application linked against libxml2
were tricked into opening a specially crafted XML file, an attacker could
cause the application to crash or possibly execute arbitrary code with the
privileges of the user invoking the program.
