CVE-2014-4496

Status: ModifiedMedium (5)—

The mach_port_kobject interface in the kernel in Apple iOS before 8.1.3 and Apple TV before 7.0.3 does not properly restrict kernel-address and heap-permutation information, which makes it easier for attackers to bypass the ASLR protection mechanism via a crafted app.

CVSS
