Descriptions

WindowServer in Apple OS X before 10.12 allows local users to obtain root access via vectors that leverage "type confusion," a different vulnerability than CVE-2016-4710.

WindowServer en Apple OS X en versiones anteriores a 10.12 permite a usuarios locales obtener acceso de root a través de vectores que desencadenan una "confusión de tipo", una vulnerabilidad diferente a CVE-2016-4710.

This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of Apple OS X. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the CoreGraphics module. The issue lies in the failure to properly validate user-supplied data which can result in a type confusion condition. An attacker can leverage this vulnerability to escalate privileges under the context of WindowServer.
