Summary:
Applications using libxml2 could be made to crash or run programs as your
login if they opened a specially crafted file.
Software Description:

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.
