How to fix?

Upgrade Debian:10 postgresql-11 to version 11.10-0+deb10u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-11 package and not the postgresql-11 package as distributed by Debian. See How to fix? for Debian:10 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).
