  script_tag(name:"insight", value:"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 [email protected]. (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)");
