CVE-2020-21469 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:14.04.
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.
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).
