How to fix?

Upgrade Ubuntu:16.04 postgresql-9.5 to version 9.5.25-0ubuntu0.16.04.1+esm6 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.

A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
