This post follows on from my previous OS X exploit tutorial which demonstrated finding a buffer overflow in an OS X application and developing a working exploit for it. The technique used in that tutorial only worked on the previous incarnation of Apple’s OS X operating system known as Leopard (10.5.x).


I stupidly mentioned at the end of my previous post that future OS X exploit would likely rely on ROP based techniques in order to bypass non-executable memory protection and achieve code execution. I was then challenged by then Offensive Security team to produce a follow up post, so the obvious next port of call was to get my previous EvoCam exploit working on Snow Leopard.
