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)
