An update that solves two vulnerabilities and has 12 fixes 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)

  • Allow YaST to select Iranian (Persian, Farsi) keyboard layout (bsc#1092920)
