Security update for systemd SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2018:3644-1 Final 1 1 2018-11-07T10:14:46Z current 2018-11-07T10:14:46Z 2018-11-07T10:14:46Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for systemd This update for systemd fixes the following issues: Security issues fixed: - CVE-2018-15688: A buffer overflow vulnerability in the dhcp6 client of systemd allowed a malicious dhcp6 server to overwrite heap memory in systemd-networkd. (bsc#1113632) - CVE-2018-15686: A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. (bsc#1113665) Non security issues fixed: - dhcp6: split assert_return() to be more debuggable when hit - core: skip unit deserialization and move to the next one when unit_deserialize() fails - core: properly handle deserialization of unknown unit types (#6476) - core: don't create Requires for workdir if 'missing ok' (bsc#1113083) - logind: use manager_get_user_by_pid() where appropriate - logind: rework manager_get_{user|session}_by_pid() a bit - login: fix user@.service case, so we don't allow nested sessions (#8051) (bsc#1112024) - core: be more defensive if we can't determine per-connection socket peer (#7329) - core: introduce systemd.early_core_pattern= kernel cmdline option - core: add missing 'continue' statement - core/mount: fstype may be NULL - journald: don't ship systemd-journald-audit.socket (bsc#1109252) - core: make 'tmpfs' dependencies on swapfs a 'default' dep, not an 'implicit' (bsc#1110445) - mount: make sure we unmount tmpfs mounts before we deactivate swaps (#7076) - detect-virt: do not try to read all of /proc/cpuinfo (bsc#1109197) - emergency: make sure console password agents don't interfere with the emergency shell - man: document that 'nofail' also has an effect on ordering - journald: take leading spaces into account in syslog_parse_identifier - journal: do not remove multiple spaces after identifier in syslog message - syslog: fix segfault in syslog_parse_priority() - journal: fix syslog_parse_identifier() - install: drop left-over debug message (#6913) - Ship systemd-sysv-install helper via the main package This script was part of systemd-sysvinit sub-package but it was wrong since systemd-sysv-install is a script used to redirect enable/disable operations to chkconfig when the unit targets are sysv init scripts. Therefore it's never been a SySV init tool. - Add udev.no-partlabel-links kernel command-line option. This option can be used to disable the generation of the by-partlabel symlinks regardless of the name used. (bsc#1089761) - man: SystemMaxUse= clarification in journald.conf(5). (bsc#1101040) - systemctl: load unit if needed in 'systemctl is-active' (bsc#1102908) - core: don't freeze OnCalendar= timer units when the clock goes back a lot (bsc#1090944) - Enable or disable machines.target according to the presets (bsc#1107941) - cryptsetup: add support for sector-size= option (fate#325697) - nspawn: always use permission mode 555 for /sys (bsc#1107640) - Bugfix for a race condition between daemon-reload and other commands (bsc#1105031) - Fixes an issue where login with root credentials was not possible in init level 5 (bsc#1091677) - Fix an issue where services of type 'notify' harmless DENIED log entries. (bsc#991901) - Does no longer adjust qgroups on existing subvolumes (bsc#1093753) - cryptsetup: add support for sector-size= option (#9936) (fate#325697 bsc#1114135) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
