Descriptions

The IOAcceleratorFamily2 interface in IOAcceleratorFamily in Apple OS X before 10.11.3 allows local users to gain privileges or cause a denial of service (memory corruption) via unspecified vectors.

La interfaz IOAcceleratorFamily2 en IOAcceleratorFamily en Apple OS X en versiones anteriores a 10.11.3 permite a usuarios locales obtener privilegios o causar una denegación de servicio (corrupción de memoria) a través de vectores no especificados.

This vulnerability allows local attackers to elevate privileges on vulnerable installations of Apple OS X. User interaction is required to exploit this vulnerability in that the target must open a malicious file.
The specific flaw exists within the IOAcceleratorFamily2 interface. The issue lies in the failure to properly test a user-supplied index to ensure it is within the bounds of an array. An attacker can leverage this to escalate their privileges and execute code under the context of the kernel.
