           This module exploits a stack-based buffer overflow vulnerability in
         i-Ftp v2.20, caused by a long time value set for scheduled download.

-        a remote attacker could execute arbitrary code on the system or cause
-        the application to crash. This module has been tested successfully on
-        Windows XP SP3.
