Detailsinfo

A vulnerability, which was classified as critical, was found in Apple Mac OS X 10.9.2 (Operating System). This affects an unknown functionality of the component IOKit Kernel. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

IOKit in Apple iOS before 7.1.1, Apple OS X through 10.9.2, and Apple TV before 6.1.1 places kernel pointers into an object data structure, which makes it easier for local users to bypass the ASLR protection mechanism by reading unspecified attributes of the object.

The weakness was published 04/22/2014 by Ian Beer with Google Project Zero as HT6207 as confirmed advisory (Website) via Zero Day Initiative (ZDI). It is possible to read the advisory at support.apple.com. The public release has been coordinated with Apple. This vulnerability is uniquely identified as CVE-2014-1320 since 01/08/2014. The exploitability is told to be difficult. Attacking locally is a requirement. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1592 according to MITRE ATT&CK. The advisory points out:

A local user can read kernel pointers, which can be used to bypass kernel address space layout randomization
