Affected Products:
  • SUSE Linux Enterprise Module for Open Buildservice Development Tools 15
  • SUSE Linux Enterprise Module for Basesystem 15

An update that solves two vulnerabilities and has 16 fixes is now available.


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 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 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)
