openSUSE Security Update : systemd (openSUSE-2018-1423)

high Nessus Plugin ID 119028

Language:

Synopsis

The remote openSUSE host is missing a security update.

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 [email protected] 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.
