iOS 9.1 Kills Pangu Jailbreak for iOS 9 – 9.0.2, patches two vulnerabilities

Apple has released iOS 9.1 final version for iPhone, iPad, and iPod Touch, which does not bring a good news for the jailbreak community. Among the addition of new features, performance improvements, and bug fixes, iOS 9.1 also kills the Pangu jailbreak by patching two vulnerabilities used by the jailbreak tool to jailbreak iOS 9 – 9.0.2 on all supported iPhone, iPad, and iPod Touch devices.

Apple has posted a listed of vulnerabilities and security flaws that the company has fixed in iOS 9.1 and credited team Pangu for finding two of them. Both of those vulnerabilities were most probably used by the team in their Pangu 9 jailbreak for iOS 9.0.2 – iOS 9.

Apple has listed several security patches in the security release notes of iOS 9.1 and has credited the “Pangu Team” for discovering two of them. Here are the vulnerabilities that have been patched in iOS 9.1 that were most probably used in the Pangu iOS 9 – iOS 9.0.2 jailbreak.

Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later
Impact: A malicious application may be able to elevate privileges
Description: A heap based buffer overflow issue existed in the DNS client library. A malicious application with the ability to spoof responses from the local configd service may have been able to cause arbitrary code execution in DNS clients.
CVE-2015-7015 : PanguTeam

Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later
Impact: A malicious application may be able to execute arbitrary code with kernel privileges
Description: A memory corruption issue existed in the kernel. This issue was addressed through improved memory handling.
CVE-2015-6979 : PanguTeam

This is indeed a bad news for the jailbreak community as it means that Pangu jailbreak won’t work on iOS 9.1 unless the team has some more vulnerabilities up its sleeves. If you’re still running iOS 9, iOS 9.0.1, or iOS 9.0.2, you can still use Pangu 9 to jailbreak your device. Do not upgrade to iOS 9, or you’ll lose your jailbreak and also be cautious of installing any jailbreak tweak or app as it may put your device into boot loop forcing you to restore it using iTunes.

However, you can still downgrade back to iOS 9.0.2, since Apple is still signing it, and re-jailbreak your device. Follow our guide on how to downgrade iOS 9.1 to iOS 9.0.2. and how to jailbreak iOS 9 – 9.0.2 with Pangu.
