Security update for systemd SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2018:0546-1 Final 1 1 2018-02-26T15:35:50Z current 2018-02-26T15:35:50Z 2018-02-26T15:35:50Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for systemd This update for systemd fixes the following issues: Security issue fixed: - CVE-2017-18078: tmpfiles: refuse to chown()/chmod() files which are hardlinked, unless protected_hardlinks sysctl is on. This could be used by local attackers to gain privileges (bsc#1077925) Non Security issues fixed: - core: use id unit when retrieving unit file state (#8038) (bsc#1075801) - cryptsetup-generator: run cryptsetup service before swap unit (#5480) - udev-rules: all values can contain escaped double quotes now (#6890) - strv: fix buffer size calculation in strv_join_quoted() - tmpfiles: change ownership of symlinks too - stdio-bridge: Correctly propagate error - stdio-bridge: remove dead code - remove bus-proxyd (bsc#1057974) - core/timer: Prevent timer looping when unit cannot start (bsc#1068588) - Make systemd-timesyncd use the openSUSE NTP servers by default Previously systemd-timesyncd used the Google Public NTP servers time{1..4}.google.com - Don't ship /usr/lib/systemd/system/tmp.mnt at all (bsc#1071224) But we still ship a copy in /var. Users who want to use tmpfs on /tmp are supposed to add a symlink in /etc/ pointing to the copy shipped in /var. To support the update path we automatically create the symlink if tmp.mount in use is located in /usr. - Enable systemd-networkd on Leap distros only (bsc#1071311) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
