iOS hacker and modder Stefan is now confirming that he is not going to hold his untethered jailbreak exploit on iOS 4.3 for too long (till iOS 4.3.1 drops-in) and might release it for primetime availability as soon it is ready.
BTW: I never said that I would wait for 4.3.1 to be released. I only said that releasing it now might burn it fast.
As predicted earlier, ASLR does not come as a blockade to achieve jailbreak. Stefan’s kernel exploit easily bypasses DEP (data execution prevention) and ASLR (address space layout randomization), two key protection mechanisms built into the newest versions of iOS 4.3.
Those who are not aware of what “Untethered” means is that it doesn’t require you to hook up your iPhone, iPad or iPod Touch to iTunes whenever you restart the device. In short – It cuts the cord! Here is the demo video.
We are assuming that Apple will release the security update within a week to fix the vulnerability discovered by Charlie Miller at Pwn2Own contest. And by that time, it would not be easier for Stefan to wrap the exploit for primetime usage.
We will update you as more information from him trickles-in.
