  Security issues fixed:

  - CVE-2018-15688: A buffer overflow vulnerability in the dhcp6 client of
  systemd allowed a malicious dhcp6 server to overwrite heap memory in
  systemd-networkd. (bsc#1113632)

  - CVE-2018-15686: A vulnerability in unit_deserialize of systemd allows an
  attacker to supply arbitrary state across systemd re-execution via
  NotifyAccess. This can be used to improperly influence systemd execution
  and possibly lead to root privilege escalation. (bsc#1113665)

  Non security issues fixed:

  - dhcp6: split assert_return() to be more debuggable when hit

  - core: skip unit deserialization and move to the next one when
  unit_deserialize() fails

  - core: properly handle deserialization of unknown unit types (#6476)

  - core: don't create Requires for workdir if 'missing ok' (bsc#1113083)

  - logind: use manager_get_user_by_pid() where appropriate

  - logind: rework manager_get_{usersession}_by_pid() a bit

  - login: fix [email protected] case, so we don't allow nested sessions (#8051)
  (bsc#1112024)

  - core: be more defensive if we can't determine per-connection socket peer
  (#7329)

  - core: introduce systemd.early_core_pattern= kernel cmdline option

  - core: add missing 'continue' statement

  - core/mount: fstype may be NULL

  - journald: don't ship systemd-journald-audit.socket (bsc#1109252)

  - core: make 'tmpfs' dependencies on swapfs a 'default' dep, not an
  'implicit' (bsc#1110445)

  - mount: make sure we unmount tmpfs mounts before we deactivate swaps
  (#7076)

  - detect-virt: do not try to read all of /proc/cpuinfo (bsc#1109197)

  - emergency: make sure console password agents don't interfere with the
  emergency shell

  - man: document that 'nofail' also has an effect on ordering

  - journald: take leading spaces into account in syslog_parse_identifier

  - journal: do not remove multiple spaces after identifier in syslog message

  - syslog: fix segfault in syslog_parse_priority()

  - journal: fix syslog_parse_identifier()

  - install: drop left-over debug message (#6913)

  - Ship systemd-sysv-install helper via the main package This script was
  part of systemd-sysvinit sub-package but it was wrong since
  systemd-sysv-install is a script used to redirect enable/disable
  operations to chkconfig when the unit targets are sysv init scripts.
  Therefore it's never been a SySV init tool.

  - Add udev.no-partlabel-links kernel command-line option. This option can
  be used to disable the generation of the by-partlabel symlinks
  regardless of the name used. (bsc#1089761)

  - man: SystemMaxUse= clar ...
