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 (OCP)
deployment for storage, retrieval, and monitoring.

(CVE-2021-44716) For more details about the security issue(s), including
the impact, a CVSS score, and other related information, refer to the CVE
page(s) listed in the References section.

Bug fixes:

* In some cases, Ceilometer metrics were not handled properly by sg-core.
This resulted in some Ceilometer metrics not being stored in Prometheus. In
this release, the processing of metrics has been enhanced to be more
robust. While the sg-core has been enhanced to support larger messages from
Ceilometer, an additional change is required to support passing the larger
messages through the sg-bridge ring buffer. The changes required to fully
support this functionality is being tracked in RHBZ#2053681. (BZ#2051615)

The Service Telemetry Framework container image provided by this update can
be downloaded from the Red Hat Container Registry at
registry.access.redhat.com. Installation instructions for your platform are
available at Red Hat Container Catalog (see References).
Dockerfiles and scripts should be amended either to refer to this new image
specifically, or to the latest image generally.
