NVD Description
Note: Versions mentioned in the description apply only to the upstream postgresql-test-rpm-macros package and not the postgresql-test-rpm-macros package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack.
