Description

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.
