Upgrade Debian:9 postgresql-9.6 to version 9.6.24-0+deb9u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream postgresql-9.6 package and not the postgresql-9.6 package as distributed by Debian.
See How to fix? for Debian:9 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.
