'Description' => %q{  
This is a simple buffer overflow for the minishare web  
server. This flaw affects all versions prior to 1.4.2. This  
is a plain stack overflow that requires a "jmp esp" to reach  
the payload, making this difficult to target many platforms  
at once. This module has been successfully tested against  
1.4.1. Version 1.3.4 and below do not seem to be vulnerable.
