bind9 vulnerability
==========================================================================

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

- - Ubuntu 18.04 LTS

Summary:

Bind could incorrectly enable recursion.

Software Description:
- - bind9: Internet Domain Name Server

Details:

Andrew Skalski discovered that Bind could incorrectly enable recursion
when the "allow-recursion" setting wasn't specified. This issue could
improperly permit recursion to all clients, contrary to expectations.

package versions:

Ubuntu 18.04 LTS:
  bind9                           1:9.11.3+dfsg-1ubuntu1.1
