This update for systemd fixes the following issues:

- CVE-2016-7796: A zero-length message received over systemd's notification socket
could make manager_dispatch_notify_fd() return an error and, as a side effect,
disable the notification handler completely. As the notification socket is
world-writable, this could have allowed a local user to perform a denial-of-service
attack against systemd. (bsc#1001765)

Additionally, the following non-security fixes are included:

- Fix HMAC calculation when appending a data object to journal. (bsc#1000435)
- Never accept file descriptors from file systems with mandatory locking enabled.
(bsc#954374)
- Do not warn about missing install info with "preset". (bsc#970293)
- Save /run/systemd/users/UID before starting user@.service. (bsc#996269)
- Make sure that /var/lib/systemd/sysv-convert/database is always initialized.
