Description

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)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
