CVE-2014-4491: Apple iPhone OS

Medium severity, CVSS 5.0. EPSS: 1.7% chance of exploitation in the next 30 days.

The extension APIs in the kernel in Apple iOS before 8.1.3, Apple OS X before 10.10.2, and Apple TV before 7.0.3 do not prevent the presence of addresses within an OSBundleMachOHeaders key in a response, 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 Mac OS X: up to and including 10.10.1
• Apple tvOS: up to and including 7.0.1
