Persits Software that reportedly is affected by a buffer overflow in
its 'AddFolder' method that can be triggered by a long argument.  If a
remote attacker can trick a user on the affected host into visiting a
specially crafted web page, this issue could be leveraged to execute
arbitrary code on the affected host subject to the user's privileges." );
