   is now available.

Description:

   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)
