CVE-2014-4496: Apple iPhone OS

Medium severity, CVSS 5.0. EPSS: 1.8% chance of exploitation in the next 30 days.

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.

Affected products

• Apple iPhone OS: up to and including 8.1.2
• Apple tvOS: up to and including 7.0.1
