SUSE-SU-2018:3644-1

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 managergetuserbypid() where appropriate
• logind: rework managerget{user|session}bypid() 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.earlycorepattern= 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 syslogparseidentifier
• journal: do not remove multiple spaces after identifier in syslog message
• syslog: fix segfault in syslogparsepriority()
• journal: fix syslogparseidentifier()
• 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)
