CVE-2015-5839 : @PanguTeam, TaiG Jailbreak Team
Apple had patched several vulnerabilities in iOS 8.4.1 used by the TaiG team in the iOS 8.1.3 – iOS 8.4 jailbreak. It is not clear if Apple has patched the vulnerability which was highlighted by the Pangu team in iOS 8.4.1.
iOS 9 Jailbreak Status
The good news is that iOS 9 has already been jailbroken. Few days back, iH8sn0w, developer of popular jailbreak tools such as Sn0wbreeze, P0sixspwn published a video to demonstrate that iOS 9 can be jailbroken. He doesn’t plan to release the iOS 9 jailbreak, so we will have to wait for Pangu or TaiG team to discover the vulnerabilities to jailbreak iOS 9. But the fact that it can be jailbroken gives us some hope that a jailbreak for iOS 9 could be released a lot sooner than the jailbreak for iOS 8 was released. Jailbreak for iOS 8 was released more than a month after it was released.
