openSUSE Security Update: Security update for systemd ______________________________________________________________________________ Announcement ID: openSUSE-SU-2018:3803-1 Rating: important References: #1106923 #1108835 #1109252 #1110445 #1111278 #1112024 #1113083 #1113632 #1113665 Cross-References: CVE-2018-15686 CVE-2018-15688 Affected Products: openSUSE Leap 42.3 ______________________________________________________________________________ An update that solves two vulnerabilities and has 7 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) - socket-util: introduce port argument in sockaddr_port() - service: fixup ExecStop for socket-activated shutdown (#4120) - service: Continue shutdown on socket activated unit on termination (#4108) (bsc#1106923) - cryptsetup: build fixes for "add support for sector-size= option" - udev-rules: IMPORT cmdline does not recognize keys with similar names (bsc#1111278) - core: keep the kernel coredump defaults when systemd-coredump is disabled - core: shorten main() a bit, split out coredump initialization - core: set RLIMIT_CORE to unlimited by default (bsc#1108835) - 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) - tmp.mount.hm4: After swap.target (#3087) - 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. This update was imported from the SUSE:SLE-12-SP2:Update update project.
