"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 [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)

  - 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.
