iOS 5.1 Jailbreak Progress Update: Pod2g Already Bypassed ASLR
For those of us following Pod2g’s 5.1 jailbreak saga, we have some more good news. It seems that Apple’s latest Address Space Layout Randomization scheme wasn’t as tough to break as anticipated. Pod2g announced on Twitter this morning that he was able to bypass ASLR. The next step of the project is to execute code on the unjailbroken devices using a ROP payload. The goal of which is to allow software to write to the phone’s kernel memory.
When Pod2g announced that he had found all the exploits required for a jailbreak on Wednesday, Grant Paul (@chpwn) cautioned his followers on Twitter that the exploits don’t mean a jailbreak exists, and that it could take months for anyone to have access to a fully working version of the jailbreak. While Pod2g’s latest breakthrough is encouraging news, keep in mind that Pod2g is working on this jailbreak in his own time for free and there’s no promised release date for any new jailbreak.
That said, for those of you stuck between iOS 5.1 and 4.3.3 there is a light at the end of the tunnel. How far away it is still remains to be seen.
