Description
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).
