How to fix?

Upgrade Ubuntu:16.04 postgresql-9.5 to version 9.5.25-0ubuntu0.16.04.1+esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-9.5 package and not the postgresql-9.5 package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption.
