"This update for systemd fixes the following issues :

  - CVE-2020-1712 (bsc#bsc#1162108) Fix a heap
    use-after-free vulnerability, when asynchronous Polkit
    queries were performed while handling Dbus messages. A
    local unprivileged attacker could have abused this flaw
    to crash systemd services or potentially execute code
    and elevate their privileges, by sending specially
    crafted Dbus messages.

  - Use suse.pool.ntp.org server pool on SLE distros
    (jsc#SLE-7683)

  - libblkid: open device in nonblock mode. (bsc#1084671)

  - udev/cdrom_id: Do not open CD-rom in exclusive mode.
    (bsc#1154256)

  - bus_open leak sd_event_source when udevadm
    trigger。 (bsc#1161436 CVE-2019-20386)

  - fileio: introduce read_full_virtual_file() for reading
    virtual files in sysfs, procfs (bsc#1133495 bsc#1159814)

  - fileio: initialize errno to zero before we do fread()

  - fileio: try to read one byte too much in
    read_full_stream()

  - logind: consider 'greeter' sessions suitable as
    'display' sessions of a user (bsc#1158485)

  - logind: never elect a session that is stopping as
    display

  - journal: include kmsg lines from the systemd process
    which exec()d us (#8078)

  - udevd: don't use monitor after manager_exit()

  - udevd: capitalize log messages in on_sigchld()

  - udevd: merge conditions to decrease indentation

  - Revert 'udevd: fix crash when workers time out after
    exit is signal caught'

  - core: fragments of masked units ought not be considered
    for NeedDaemonReload (#7060) (bsc#1156482)

  - udevd: fix crash when workers time out after exit is
    signal caught

  - udevd: wait for workers to finish when exiting
    (bsc#1106383)

  - Improve bash completion support (bsc#1155207)

  - shell-completion: systemctl: do not list template units
    in (re,)start

  - shell-completion: systemctl: pass current word to all
    list_unit*

  - bash-completion: systemctl: pass current partial unit to
    list-unit* (bsc#1155207)

  - bash-completion: systemctl: use systemctl --no-pager

  - bash-completion: also suggest template unit files

  - bash-completion: systemctl: add missing options and
    verbs

  - bash-completion: use the first argument instead of the
    global variable (#6457)

  - networkd: VXLan Make group and remote variable separate
    (bsc#1156213)

  - networkd: vxlan require Remote= to be a non multicast
    address (#8117) (bsc#1156213)

  - fs-util: let's avoid unnecessary strerror()

  - fs-util: introduce inotify_add_watch_and_warn() helper

  - ask-password: improve log message when inotify limit is
    reached (bsc#1155574)

  - shared/install: failing with -ELOOP can be due to the
    use of an alias in install_error() (bsc#1151377)

  - man: alias names can't be used with enable command
    (bsc#1151377)

  - Add boot option to not use swap at system start
    (jsc#SLE-7689)

  - Allow YaST to select Iranian (Persian, Farsi) keyboard
    layout (bsc#1092920) This update was imported from the
    SUSE:SLE-15:Update update project."
