1. Summary:
An update for cluster-network-operator-container,
cluster-version-operator-container, elasticsearch-operator-container,
logging-kibana6-container, and
ose-cluster-svcat-controller-manager-operator-container is now available

the log data.

* kibana: XSS in TSVB visualization (ESA-2020-08) (CVE-2020-7015)
* golang.org/x/text: Possibility to trigger an infinite loop in
