Apparently, Apple is strengthening its upcoming iOS 4.3 firmware with the addition of ASLR (Address Space Layout Randomization). ASLR is a computer security and a hacker’s nightmare. With the introduction of this security measure, jailbreakers would find it difficult to locate the target addresses as the virtual memory area is increased. While this new move from Apple would pose a stiff challenge to jailbreakers , it has been welcomed by many of them as there have been several tweets about the same saying, “this would be some fun.”
With the untethered iOS 4.2.1 jailbreak yet to be released, the news about a much secured 4.3 could be daunting to all the jailbreakers across the world. The beta version of iOS 4.3 was launched two weeks ago and the firmware version is going to be made available to the public very soon.
