   An update that solves two vulnerabilities and has 7 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 at .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)
   - socket-util: introduce port argument in sockaddr_port()
   - service: fixup ExecStop for socket-activated shutdown (#4120)
   - service: Continue shutdown on socket activated unit on termination
     (#4108) (bsc#1106923)
   - cryptsetup: build fixes for "add support for sector-size= option"
   - udev-rules: IMPORT cmdline does not recognize keys with similar names
     (bsc#1111278)
   - core: keep the kernel coredump defaults when systemd-coredump is disabled
   - core: shorten main() a bit, split out coredump initialization
   - core: set RLIMIT_CORE to unlimited by default (bsc#1108835)
   - 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)
   - tmp.mount.hm4: After swap.target (#3087)

   - 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.
