● 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-2014-4455 : TaiG Jailbreak Team

● 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-2014-4491 : @PanguTeam, Stefan Esser
