iOS 4.3 Proves to Be a Challenge: Apple Adds ASLR Protection
Little birdies have been tweeting about iOS 4.3 untethered
jailbreak progresses, and it sounds like it might be a little bit tougher than expected, which is actually kind of sad as we are being teased with new features, yet again, being added to iOS 4.3. Whether or not those features are worth losing a jailbreak is yet to be determined. However the scenario, it has been discovered that Apple has added ASLR (Address Space Layout Randomization).
This might sound familiar to some of you, as this is what Antid0te
was all about. Remember that tool that was going to add an extra layer of security to your jailbroken iDevice? Antid0te used ASLR protection, but it was to be installed AFTER you were jailbroken. It almost seems as though Apple is always keeping an eye on what we are doing in the jailbreaking community.
However the case, @comex
has chimed in and said “Heh, I think I can work around ASLR in this case, but it's cool that they're using it. I should see if iOS 4.3 breaks anything else...” via twitter.
So while it may seem that jailbreaking iOS 4.3 may prove to be more difficult, it certainly isn’t impossible.
While we wait patiently for an untethered iOS 4.2.1 release, may we dream of the days of jailbreaking iOS 4.3. Until then...
