An update for logging-kibana5-container and
openshift-enterprise-registry-container is now available for Red Hat
OpenShift Container Platform 3.11.
Red Hat Product Security has rated this update as having a security impact
of Moderate. 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.
OpenShift Container Platform components are primarily written in Go

text operations, such as character encodings, text transformations, and
locale-specific text handling.

cluster logging. It is a browser-based console interface to query,
discover, and visualize
the log data.
