An update that solves four vulnerabilities and has 7 fixes is now available.


This update for systemd provides the following fixes:
Security issues fixed:

  • CVE-2018-16864, CVE-2018-16865: Fixed two memory corruptions through attacker-controlled alloca()s (bsc#1120323)
  • CVE-2018-16866: Fixed an information leak in journald (bsc#1120323)
  • CVE-2018-6954: Fix mishandling of symlinks present in non-terminal path components (bsc#1080919)
  • Fixed an issue during system startup in relation to encrypted swap disks (bsc#1119971)

Non-security issues fixed:
  • pam_systemd: Fix 'Cannot create session: Already running in a session' (bsc#1111498)
  • systemd-vconsole-setup: vconsole setup fails, fonts will not be copied to tty (bsc#1114933)
  • systemd-tmpfiles-setup: symlinked /tmp to /var/tmp breaking multiple units (bsc#1045723)
  • Fixed installation issue with /etc/machine-id during update (bsc#1117063)
  • btrfs: qgroups are assigned to parent qgroups after reboot (bsc#1093753)
  • logind: Stop managing VT switches if no sessions are registered on that VT. (bsc#1101591)
  • udev: Downgrade message when settting inotify watch up fails. (bsc#1005023)
  • udev: Ignore the exit code of systemd-detect-virt for memory hot-add. In SLE-12-SP3, 80-hotplug-cpu-mem.rules has a memory hot-add rule that uses systemd-detect-virt to detect non-zvm environment. The systemd-detect-virt returns exit failure code when it detected _none_ state. The exit failure code causes that the hot-add memory block can not be set to online. (bsc#1076696)
