"This update for systemd provides the following fixes :

Security issues fixed :

CVE-2018-16864, CVE-2018-16865: Fixed two memory corruptions through
attacker-controlled alloca()s (bsc#1120323)

CVE-2018-16866: Fixed an information leak in journald (bsc#1120323)

Fixed an issue during system startup in relation to encrypted swap
disks (bsc#1119971)

Non-security issues fixed: core: Queue loading transient units after
setting their properties. (bsc#1115518)

logind: Stop managing VT switches if no sessions are registered on
that VT. (bsc#1101591)

terminal-util: introduce vt_release() and vt_restore() helpers.

terminal: Unify code for resetting kbd utf8 mode a bit.

terminal Reset should honour default_utf8 kernel setting.

logind: Make session_restore_vt() static.

udev: Downgrade message when settting inotify watch up fails.
(bsc#1005023)

log: Never log into foreign fd #2 in PID 1 or its pre-execve()
children. (bsc#1114981)

udev: Ignore the exit code of systemd-detect-virt for memory hot-add.
In SLE-12-SP3, 80-hotplug-cpu-mem.rules has a memory hot-add rule that
uses systemd-detect-virt to detect non-zvm environment. The
systemd-detect-virt returns exit failure code when it detected _none_
state. The exit failure code causes that the hot-add memory block can
not be set to online. (bsc#1076696)

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."
