'Name' => 'Novell iPrint Client ActiveX Control call-back-url Buffer Overflow',

'Description'=> %q{

This module exploits a stack-based buffer overflow in Novell iPrint Client 5.42.

When sending an overly long string to the 'call-back-url' parameter in an

op-client-interface-version action of ienipp.ocx an attacker may be able to

execute arbitrary code.
