TITLE

Apple OS X Privileged vulnerability in graphics driver subsystem

Trust: 0.8

DESCRIPTION

The Graphics Drivers subsystem in Apple OS X before 10.11.1 allows local users to gain privileges or cause a denial of service (kernel memory corruption) via unspecified vectors. Apple Mac OS X is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, cause denial-of-service conditions, bypass security restrictions and perform unauthorized actions. This may aid in other attacks. Graphics Drivers is one of the graphics driver components
