Descriptions

The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.

Una función execve en el kernel de Linux, posiblemente versión 2.6.30-rc6 y anteriores, no borra apropiadamente el puntero de current-)clear_child_tid, lo que permite a los usuarios locales causar una denegación de servicio (corrupción de memoria) o posiblemente alcanzar privilegios por medio de un sistema de clonación que llama con CLONE_CHILD_SETTID o CLONE_CHILD_CLEARTID habilitadas, que no son manejados apropiadamente durante la creación y salida de hilos (subprocesos).
