iOS 8.3 Makes Jailbreaking Impossible With 40 Security Patches
iOS 8.3 was rolled out yesterday and comes with some bad news for all the Apple users heavily dependent on untethered jailbreaks. iOS 8.3 has come with a whopping 40 security patches and Apple seems to have finally gained the upper hand as every version of iOS was jailbroken up to iOS 8.1.2 so far.
Apple’s support document has shed light on the security patches in iOS 8.3, some of them being:
One of the loopholes in previous iOS versions was that it allowed access to an interface which allowed attempts to confirm the user’s password. This issue was resolved with improved entitlement checking.
Previously, an issue existed in the relative path evaluation logic of the backup system which could be used to access restricted areas of the system. This issue was catered to through improved path evaluation.
There existed a race condition existed in one of the system calls of OS’ kernel, which could be exploited to cause a system denial of service. This has now been solved through improved state management.
As a veteran MuscleNerd revealed on Twitter, iOS 8.3 has taken a pretty long jump in terms of volume compared to iOS 7’s leap to iOS 8. With exploiters like Pangu, PP and TaiG all keeping the Cupertino company on its toes, and Cydia tweaks being enjoyed by all fans in the first few months of iOS 8’s arrival, Apple has hit back hard with the release of iOS 8.3. Its chances of being jailbroken are actually converged to nil right now, and it seems it is to remain that way for a long time to come.
