How to fix?

There is no fixed version for Ubuntu:14.04 postgresql-9.3.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-9.3 package and not the postgresql-9.3 package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

An issue was discovered in PostgreSQL 12.2 allows attackers to cause a denial of service via repeatedly sending SIGHUP signals. NOTE: this is disputed by the vendor because untrusted users cannot send SIGHUP signals; they can only be sent by a PostgreSQL superuser, a user with pg_reload_conf access, or a user with sufficient privileges at the OS level (the postgres account or the root account).
