Detailsinfo

A vulnerability was found in Apple Mac OS X 10.8.5/10.9.5/10.10/10.10.1 (Operating System). It has been classified as critical. This affects an unknown part of the component Intel Graphics Driver. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Intel Graphics Driver in Apple OS X before 10.10.2 allows local users to gain privileges via unspecified vectors, a different vulnerability than CVE-2014-8819 and CVE-2014-8820.

The weakness was presented 01/27/2015 by Ian Beer with Google Project Zero as HT204244 as confirmed advisory (Website). It is possible to read the advisory at support.apple.com. This vulnerability is uniquely identified as CVE-2014-8821 since 11/14/2014. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The advisory points out:

Multiple vulnerabilities existed in the Intel graphics driver, the most serious of which may have led to arbitrary code execution with system privileges. This update addresses the issues through additional bounds checks.
