'Name' => 'Novell iPrint Client ActiveX Control Date/Time Buffer Overflow',
'Description' => %q{
This module exploits a stack 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.
