'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.
