"This update for systemd fixes the following issues :

Security issues fixed :

CVE-2018-6954: Fixed a vulnerability in the symlink handling of
systemd-tmpfiles which allowed a local user to obtain ownership of
arbitrary files (bsc#1080919).

CVE-2019-3842: Fixed a vulnerability in pam_systemd which allowed a
local user to escalate privileges (bsc#1132348).

CVE-2019-6454: Fixed a denial of service caused by long dbus messages
(bsc#1125352).

Non-security issues fixed: systemd-coredump: generate a stack trace of
all core dumps (jsc#SLE-5933)

udevd: notify when max number value of children is reached only once
per batch of events (bsc#1132400)

sd-bus: bump message queue size again (bsc#1132721)

core: only watch processes when it's really necessary (bsc#955942
bsc#1128657)

rules: load drivers only on 'add' events (bsc#1126056)

sysctl: Don't pass null directive argument to '%s' (bsc#1121563)

Do not automatically online memory on s390x (bsc#1127557)

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."
