Apple released iOS 8.4.1 earlier today which included several bug fixes and improvements for Apple Music. We’ve some bad news for jailbreakers as it looks like iOS 8.4.1 patches several vulnerabilities used by the TaiG team in their jailbreak tool.

Apple has listed several security patches in the security release notes of iOS 8.4.1 and has credited the “TaiG Jailbreak Team” for discovering eight of them. Here are the vulnerabilities that have been patched in iOS 8.4.1 that were used in the TaiG iOS 8.4 – iOS 8.1.3 jailbreak.

  • AppleFileConduit: Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and laterImpact: A maliciously crafted afc command may allow access to protected parts of the filesystemDescription: An issue existed in the symbolic linking mechanism of afc. This issue was addressed by adding additional path checks.CVE-IDCVE-2015-5746 : evad3rs, TaiG Jailbreak Team
  • Air Traffic: Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and laterImpact: AirTraffic may have allowed access to protected parts of the filesystemDescription: A path traversal issue existed in asset handling. This was addressed with improved validation.CVE-IDCVE-2015-5766 : TaiG Jailbreak Team
  • Backup: Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and laterImpact: A malicious application may be able to create symlinks to protected regions of the diskDescription: An issue existed within the path validation logic for symlinks. This issue was addressed through improved path sanitization.CVE-IDCVE-2015-5752 : TaiG Jailbreak Team
  • Code Signing: Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and laterImpact: A malicious application may be able to execute unsigned codeDescription: An issue existed that allowed unsigned code to be appended to signed code in a specially crafted executable file. This issue was addressed through improved code signature validation.CVE-IDCVE-2015-3806 : TaiG Jailbreak Team
  • Code Signing: Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and laterImpact: A specially crafted executable file could allow unsigned, malicious code to executeDescription: An issue existed in the way multi-architecture executable files were evaluated that could have allowed unsigned code to be executed. This issue was addressed through improved validation of executable files.CVE-IDCVE-2015-3803 : TaiG Jailbreak Team
  • Code Signing: Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and laterImpact: A local user may be able to execute unsigned codeDescription: A validation issue existed in the handling of Mach-O files. This was addressed by adding additional checks.CVE-IDCVE-2015-3802 : TaiG Jailbreak TeamCVE-2015-3805 : TaiG Jailbreak Team
  • IOHIDFamily: Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and laterImpact: A local user may be able to execute arbitrary code with system privilegesDescription: A buffer overflow issue existed in IOHIDFamily. This issue was addressed through improved memory handling.CVE-IDCVE-2015-5774 : TaiG Jailbreak Team

iOS 8.4.1 should also kill the PP Jailbreak, which was released for to jailbreak iOS 8.1.3 – iOS 8.4. This means that TaiG jailbreak and PP jailbreak cannot be used to jailbreak iOS 8.4.1 currently. You can still use them to jailbreak your device on iOS 8.4 or lower.

We’ll have to wait and see if the TaiG team will release a jailbreak for iOS 8.4.1 now that most of the vulnerabilities used in the TaiG jailbreak have been fixed, especially with iOS 9 just round the corner.

It goes without saying that jailbreakers should avoid upgrading to iOS 8.4.1 and be extremely careful while installing jailbreak tweaks.

If you’re on iOS 8.4 or lower then it may be a good idea to install iOS 8.4 manually and jailbreak your device using PP or TaiG jailbreak. If you need help then check our tutorial:
