Posted Nov 10, 2021
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2021-4582-02 - Service Telemetry Framework provides automated collection of measurements and data from remote clients, such as Red Hat OpenStack Platform or third-party nodes. STF then transmits the information to a centralized, receiving Red Hat OpenShift Container Platform deployment for storage, retrieval, and monitoring. Security fixes: golang: crypto/tls: certificate of wrong type is causing TLS client to panic.
