Voila! The long cherished jailbreak is around the corner. Pod2g has finally bypassed the ASLR at bootup which was lurking the release of iPhone 4S, iPad 3 (the new iPad) and iPad 2 untethered iOS 5.1 jailbreak. Cyril (aka Pod2g) confirmed few minutes back via twitter – “ASLR seems bypassed! Weird machines FTW. Time to ROP the payload”.
The ROP (Return Oriented Programming) payload actually abuses vulnerability in IOSurface.framework. This vulnerability allows a normal process to have access to kernel memory with write privileges. By his tweet we can assume that technical hurdles for iOS 5.1 untethered jailbreak have been ironed out completely.
Though this doesn’t mean we’ll see a jailbreak in the next few days or so, it does mean @pod2g is heading toward a perfect jailbreak. After rigorous testing, pod2g will likely package the exploit into greenpois0n Absinthe which might take few more days before it is ready for public release. We, therefore, request you to stay calm since no precise ETA has been shared.
Warning: Apple might release iOS 5.2 or an incremental iOS 5.1.1 software update within a week or two. Be sure you hold off on upgrading to any upcoming iOS update until pod2g release its jailbreak.
Stay tuned for updates as they happen!
