How to fix?

Upgrade Ubuntu:18.04 postgresql-common to version 190ubuntu0.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-common package and not the postgresql-common package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 relevant fixed versions and status.

The pg_ctlcluster script in postgresql-common in versions prior to 210 didn't drop privileges when creating socket/statistics temporary directories, which could result in local privilege escalation.
