"An security update is now available for Red Hat OpenShift Container
Platform 3.9.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Red Hat OpenShift Container Platform is Red Hat's cloud computing
Kubernetes application platform solution designed for on-premise or
private cloud deployments.

This advisory contains RPM packages for Red Hat OpenShift Container
Platform 3.9, which have been rebuilt with an updated version of
golang.

Security Fix(es) :

* HTTP/2: flood using PING frames results in unbounded memory growth
(CVE-2019-9512)

* HTTP/2: flood using HEADERS frames results in unbounded memory
growth (CVE-2019-9514)

* kubernetes: API server allows access to cluster-scoped custom
resources as if resources were namespaced (CVE-2019-11247)

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