Descriptions

The posix_spawn system call in the XNU kernel in Apple Mac OS X 10.8.x does not prevent use of the _POSIX_SPAWN_DISABLE_ASLR and _POSIX_SPAWN_ALLOW_DATA_EXEC flags for setuid and setgid programs, which allows local users to bypass intended access restrictions via a wrapper program that calls the posix_spawnattr_setflags function.

La llamada al sistema posix_spawn en el kernel de XNU en Apple Mac OS X v10.8.x no previene el uso de los flags _POSIX_SPAWN_DISABLE_ASLR y _POSIX_SPAWN_ALLOW_DATA_EXEC para programas setuid y setguid, lo que permite a usuarios locales eludir las restricciones de acceso mediante un programa "wrapper" que llama a la función posix_spawnattr_setflags.
