iOS 8.1.3 kills TaiG Jailbreak; most likely PP Jailbreak as well

Apple has posted a support page on the security content of the just-released iOS 8.1.3, confirming fears that the firmware effectively breaks the TaiG jailbreak tool. In the page, the company credits the TaiG Jailbreak Team for discovering four vulnerabilities patched in the update.
Apple has listed the four security patches in the security release notes of iOS 8.1.3, and has credited the “TaiG Jailbreak Team” for discovering them.
AppleFileConduitAvailable for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later
Impact: A maliciously crafted afc command may allow access to protected parts of the filesystem
Description: A vulnerability existed in the symbolic linking mechanism of afc. This issue was addressed by adding additional path checks.
CVE-ID
CVE-2014-4480 : TaiG Jailbreak Team
dyld
Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later
Impact: A local user may be able to execute unsigned code
Description: A state management issue existed in the handling of Mach-O executable files with overlapping segments. This issue was addressed through improved validation of segment sizes.
CVE-ID
CVE-2014-4455 : TaiG Jailbreak Team
OHIDFamily
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 system privileges
Description: A buffer overflow existed in IOHIDFamily. This issue was addressed through improved size validation.
CVE-ID
CVE-2014-4487 : TaiG Jailbreak Team
Kernel
Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later
Impact: Maliciously crafted or compromised iOS applications may be able to determine addresses in the kernel
Description: The mach_port_kobject kernel interface leaked kernel addresses and heap permutation value, which may aid in bypassing address space layout randomization protection. This was addressed by disabling the mach_port_kobject interface in production configurations.
CVE-ID
CVE-2014-4496 : TaiG Jailbreak Team
In addition, Apple has also patched a vulnerability that discovered by hacker and security researcher Stefan Esser, and was used previously in the Pangu jailbreak, and was used in the TaiG jailbreak.
Kernel
Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later
Impact: Maliciously crafted or compromised iOS applications may be able to determine addresses in the kernel
Description: An information disclosure issue existed in the handling of APIs related to kernel extensions. Responses containing an OSBundleMachOHeaders key may have included kernel addresses, which may aid in bypassing address space layout randomization protection. This issue was addressed by unsliding the addresses before returning them.
CVE-ID
CVE-2014-4491 : @PanguTeam, Stefan Esser
The TaiG jailbreak for iOS 8.1.1 debuted on November 28 of last year, just a week after iOS 8.1.1 landed. There’s no word yet on when/if it will be updated, but as always, we recommend staying away from iOS 8.1.3 until a working jailbreak for the new firmware is announced.
