______________________________________________________________________________

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

Description:

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)
