1. Summary:
An update for atomic-openshift, atomic-openshift-web-console, and cri-o is
now available for Red Hat OpenShift Container Platform 3.11.

3. Description:
Red Hat OpenShift Container Platform is Red Hat's cloud computing
Kubernetes application platform solution designed for on-premise or private
cloud deployments.
Security Fix(es):
* cri-o: A flaw was found in cri-o that can result in container management
(conmon) processes being killed if a workload process triggers an
out-of-memory (OOM) condition for the cgroup. (CVE-2019-14891)
* nodejs-minimist: Prototype pollution allows adding or modifying
properties of Object.prototype using a `constructor` or `__proto__`
payload. (CVE-2020-7598)
* kubernetes: Use of unbounded 'client' label in apiserver_request_total
allows repeated, crafted HTTP requests to exhaust available memory and
cause a crash. (CVE-2020-8552)
* kubernetes: A flaw was found in Kubernetes that allows attackers on
adjacent networks to reach services exposed on localhost ports and gain
privileges or access confidential information for any services listening on
localhost ports that are not protected by authentication. (CVE-2020-8558)
* proglottis/gpgme: A use-after-free vulnerability was found in the Go
GPGME wrapper library, github.com/proglottis/gpgme. (CVE-2020-8945)
* openshift/console: A flaw allowed text injection on error pages with a
crafted URL. (CVE-2020-10715)
