CVE-2018-1049

In systemd prior to 234 a race condition exists between .mount and .automount units such that automount requests from kernel may not be serviced by systemd resulting in kernel holding the mountpoint and any processes that try to use said mount will hang. A race condition like this may lead to denial of service, until mount points are unmounted.

A race condition like this may lead to denial of service, until mount points are unmounted.

En systemd en versiones anteriores a la 234, existe una condición de carrera entre las unidades .mount y .automount, de forma que las peticiones automount del kernel podrían no ser ofrecidas por systemd. Esto resulta en que el kernel retiene el mountpoint y cualquier proceso que intente emplear este mount se bloqueará. Una condición de carrera como esta podría conducir a una denegación de servicio (DoS) hasta que los puntos de montaje se desmonten.
