   An update that solves two vulnerabilities and has 16 fixes
   is now available.

Description:

   This update for systemd fixes the following issues:

   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_{user|session}_by_pid() a bit
   - login: fix user@.service 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= clarification in journald.conf(5). (bsc#1101040)
   - systemctl: load unit if needed in "systemctl is-active" (bsc#1102908)
   - core: don't freeze OnCalendar= timer units when the clock goes back a
     lot (bsc#1090944)
   - Enable or disable machines.target according to the presets (bsc#1107941)
   - cryptsetup: add support for sector-size= option (fate#325697)
   - nspawn: always use permission mode 555 for /sys (bsc#1107640)
   - Bugfix for a race condition between daemon-reload and other commands
     (bsc#1105031)
   - Fixes an issue where login with root credentials was not possible in
     init level 5 (bsc#1091677)
   - Fix an issue where services of type "notify" harmless DENIED log
     entries. (bsc#991901)
   - Does no longer adjust qgroups on existing subvolumes (bsc#1093753)
   - cryptsetup: add support for sector-size= option (#9936) (fate#325697
     bsc#1114135)
