Detailsinfo

A vulnerability has been found in Apple Mac OS X up to 10.11.4 (Operating System) and classified as critical. Affected by this vulnerability is some unknown processing of the component IOAcceleratorFamily. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability.

The weakness was disclosed 05/16/2016 by Ian Beer (moony li) with Google Project Zero as HT206567 as confirmed advisory (Website). The advisory is shared at support.apple.com. This vulnerability is known as CVE-2016-1819 since 01/13/2016. An attack has to be approached locally. Required for exploitation is a single authentication. It demands that the victim is doing some kind of user interaction. Technical details are unknown but a public exploit is available. The advisory points out:

Multiple memory corruption issues were addressed through improved memory handling.

A public exploit has been developed by Google Security Research and been published 4 weeks after the advisory. It is possible to download the exploit at exploit-db.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 91311 (Apple TV < 9.2.1 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Misc. and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 122912 (Apple Mac OS X v10.11.5 and Security Update 2016-003 Not Installed (APPLE-SA-2016-05-16-4)).

Upgrading to version 10.11.5 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (39928), Tenable (91311) and SecurityFocus (BID 90694†). The entries VDB-87425, VDB-87434, VDB-87435 and VDB-87436 are pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
