Descriptions
Race condition in the kernel in Apple iOS before 9.3 and OS X before 10.11.4 allows attackers to execute arbitrary code in a privileged context via a crafted app.
Condición de carrera en el kernel en Apple iOS en versiones anteriores a 9.3 y OS X en versiones anteriores a 10.11.4 permite a atacantes ejecutar cógido arbitrario en un contexto privilegiado a través de una app manipulada.
The code responsible for loading a suid-binary following a call to the execve syscall invalidates the task port after first swapping the new vm_map into the old task object leaving a short race window where we can manipulate the memory of the euid(0) process before the old task port is destroyed.
