   An update that solves one vulnerability and has 10 fixes is
   now available.

Description:


   This update for systemd fixes the following security issue:

   - 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. (bsc#982211)
   - Remove daylight saving time handling and tzfile parser. (bsc#990074)
   - Make sure directory watch is started before cryptsetup. (bsc#987173)
   - Introduce sd_pid_notify() and sd_pid_notifyf() APIs. (bsc#987857)
   - Set KillMode=mixed for our daemons that fork worker processes.
   - Add nosuid and nodev options to tmp.mount.
   - Don't start console-getty.service when /dev/console is missing.
     (bsc#982251)
   - Correct segmentation fault in udev/path_id due to missing NULL check.
     (bsc#982210)
