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.
