[USN-3466-1] systemd vulnerability

Ubuntu Security Notice USN-3466-1

systemd vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.10
- Ubuntu 17.04


systemd could be made to temporarily stop responding if it received
specially crafted network traffic.

Software Description:
- systemd: system and service manager


Karim Hossen & Thomas Imbert discovered that systemd-resolved incorrectly
handled certain DNS responses. A remote attacker could possibly use this
issue to cause systemd to temporarily stop responding, resulting in a
denial of service.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 17.10:
  systemd                         234-2ubuntu12.1

Ubuntu 17.04:
  systemd                         232-21ubuntu7.1

In general, a standard system update will make all the necessary changes.
