Descriptions

Grand Central Dispatch in Apple iOS before 9.1, OS X before 10.11.1, and watchOS before 2.0.1 allows attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted package that is mishandled during dispatch calls.

Grand Central Dispatch en Apple iOS en versiones anteriores a 9.1, OS X en versiones anteriores a 10.11.1 y watchOS en versiones anteriores a 2.0.1 permite a atacantes ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de un paquete manipulado que no se maneja correctamente al despacharse llamadas.

iOS 9.1 is now available and addresses arbitrary code execution, cookies being overwritten, heap based buffer overflow, and various other vulnerabilities.
