Detailsinfo

A vulnerability, which was classified as problematic, was found in Apple Mac OS X up to 10.9.3 (Operating System). This affects some unknown functionality of the component IOAcceleratorFamily. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

The IntelAccelerator driver in the IOAcceleratorFamily subsystem in Apple iOS before 8 and Apple TV before 7 allows attackers to cause a denial of service (NULL pointer dereference and device restart) via a crafted application.

The weakness was disclosed 10/16/2014 by Felipe Andres Manzano (cunzhang) with Adlab of Venustech as HT6535 as confirmed advisory (Website). It is possible to read the advisory at support.apple.com.
