"This update for systemd fixes the following issues: Security issue
fixed :

  - CVE-2017-18078: tmpfiles: refuse to chown()/chmod()
    files which are hardlinked, unless protected_hardlinks
    sysctl is on. This could be used by local attackers to
    gain privileges (bsc#1077925) Non Security issues 
fixed :

  - core: use id unit when retrieving unit file state
    (#8038) (bsc#1075801)

  - cryptsetup-generator: run cryptsetup service before swap
    unit (#5480)

  - udev-rules: all values can contain escaped double quotes
    now (#6890)

  - strv: fix buffer size calculation in strv_join_quoted()

  - tmpfiles: change ownership of symlinks too

  - stdio-bridge: Correctly propagate error

  - stdio-bridge: remove dead code

  - remove bus-proxyd (bsc#1057974)

  - core/timer: Prevent timer looping when unit cannot start
    (bsc#1068588)

  - Make systemd-timesyncd use the openSUSE NTP servers by
    default Previously systemd-timesyncd used the Google
    Public NTP servers time{1..4}.google.com

  - Don't ship /usr/lib/systemd/system/tmp.mnt at all
    (bsc#1071224) But we still ship a copy in /var. Users
    who want to use tmpfs on /tmp are supposed to add a
    symlink in /etc/ pointing to the copy shipped in /var.
    To support the update path we automatically create the
    symlink if tmp.mount in use is located in /usr.

  - Enable systemd-networkd on Leap distros only
    (bsc#1071311)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
