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.
