Descriptions

The wait_task_stopped function in the Linux kernel before 2.6.23.8 checks a TASK_TRACED bit instead of an exit_state value, which allows local users to cause a denial of service (machine crash) via unspecified vectors. NOTE: some of these details are obtained from third party information.

La función wait_task_stopped en el kernel de Linux versiones anteriores a 2.6.23.8 comprueba un bit TASK_TRACED en vez de un valor exit_state, lo cual permite a usuarios locales provocar una denegación de servicio (caída de máquina) mediante vectores no especificados. NOTA: algunos de estos detalles se han obtenido de información de terceros.
