Details

Juri Aedla discovered that libxml2 incorrectly handled certain memory
operations. 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.
