  					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 buffer 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.
