dns-root-data update

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

- Ubuntu 17.10
- Ubuntu 16.04 LTS


The list of trust anchors has been updated.

Software Description:
- dns-root-data: DNS root data including root zone and DNSSEC key


This update adds the latest DNSSEC validation trust anchor required for the
upcoming Root Zone KSK Rollover and refreshes the list of root hints.

Update instructions:

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

Ubuntu 17.10:
  dns-root-data                   2018013001~17.10.1

Ubuntu 16.04 LTS:
  dns-root-data                   2018013001~16.04.1

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