'Name' => 'Novell iPrint Client ActiveX Control Date/Time Buffer Overflow',

'Description'=> %q{

This module exploits a stack buffer overflow in Novell iPrint Client 5.30. When

passing a specially crafted date/time string via certain parameters to ienipp.ocx

an attacker can execute arbitrary code.

NOTE: The "operation" variable must be set to a valid command in order to reach this

vulnerability.
