Detailsinfo

A vulnerability, which was classified as critical, was found in Apple Mac OS X up to 10.11.5 (Operating System). This affects an unknown function of the component CoreGraphics. The manipulation with an unknown input leads to a out-of-bounds vulnerability (Kernel Memory). CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

CoreGraphics in Apple OS X before 10.11.6 allows local users to obtain sensitive information from kernel memory and consequently gain privileges, or cause a denial of service (out-of-bounds read), via unspecified vectors.

The weakness was presented 07/18/2016 by Stefan Esser with Zero Day Initiative as HT206903 as confirmed advisory (Website). The advisory is shared at support.apple.com. This vulnerability is uniquely identified as CVE-2016-4652 since 05/11/2016. The exploitability is told to be easy. An attack has to be approached locally. The successful exploitation requires a authentication. Neither technical details nor an exploit are publicly available. The advisory points out:

An out-of-bounds read issue existed that led to the disclosure of kernel memory. This was addressed through improved input validation.

The vulnerability scanner Nessus provides a plugin with the ID 92496 (Mac OS X 10.11.x < 10.11.6 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks and running in the context c. The commercial vulnerability scanner Qualys is able to test this issue with plugin 370095 (Apple Mac OS X v10.11.6 and Security Update 2016-004 Not Installed (APPLE-SA-2016-07-18-1)).
