'Name' => 'Novell iPrint Client ActiveX Control debug Buffer Overflow',
'Description' => %q{
This module exploits a stack-based buffer overflow in Novell iPrint Client 5.40.
When sending an overly long string to the 'debug' parameter in ExecuteRequest()
property of ienipp.ocx an attacker may be able to execute arbitrary code.
