systemd-resolved through 233 allows remote attackers to cause a denial of service (daemon crash) via a crafted DNS response with an empty question section.

An update of the systemd package has been released.

This update for systemd provides several fixes and enhancements.
Security issues fixed :

  - CVE-2017-9217: NULL pointer dereferencing that could     lead to resolved aborting. (bsc#1040614)

  - CVE-2017-9445: Possible out-of-bounds write triggered by     a specially crafted TCP payload from a DNS server.
    (bsc#1045290) The update also fixed several non-security     bugs :

  - core/mount: Use the '-c' flag to not canonicalize paths     when calling /bin/umount

  - automount: Handle expire_tokens when the mount unit     changes its state (bsc#1040942)

  - automount: Rework propagation between automount and     mount units

  - build: Make sure tmpfiles.d/systemd-remote.conf get     installed when necessary

  - build: Fix systemd-journal-upload installation

  - basic: Detect XEN Dom0 as no virtualization     (bsc#1036873)

  - virt: Make sure some errors are not ignored

  - fstab-generator: Do not skip Before= ordering for noauto     mountpoints

  - fstab-gen: Do not convert device timeout into seconds     when initializing JobTimeoutSec

  - core/device: Use JobRunningTimeoutSec= for device units     (bsc#1004995)

  - fstab-generator: Apply the _netdev option also to device     units (bsc#1004995)

  - job: Add JobRunningTimeoutSec for JOB_RUNNING state     (bsc#1004995)

  - job: Ensure JobRunningTimeoutSec= survives serialization     (bsc#1004995)

  - rules: Export NVMe WWID udev attribute (bsc#1038865)

  - rules: Introduce disk/by-id (model_serial) symbolic     links for NVMe drives

  - rules: Add rules for NVMe devices

  - sysusers: Make group shadow support configurable     (bsc#1029516)

  - core: When deserializing a unit, fully restore its     cgroup state (bsc#1029102)

  - core: Introduce     cg_mask_from_string()/cg_mask_to_string()

  - core:execute: Fix handling failures of calling fork() in     exec_spawn() (bsc#1040258)

  - Fix systemd-sysv-convert when a package starts shipping     service units (bsc#982303) The database might be missing     when upgrading a package which was shipping no sysv init     scripts nor unit files (at the time

    --save was called) but the new version start shipping     unit files.

  - Disable group shadow support (bsc#1029516)

  - Only check signature job error if signature job exists     (bsc#1043758)

  - Automounter issue in combination with NFS volumes     (bsc#1040968)

  - Missing symbolic link for SAS device in     /dev/disk/by-path (bsc#1040153)

  - Add minimal support for boot.d/* scripts in     systemd-sysv-convert (bsc#1046750)
