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.
