1. Summary:
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.
2. Description:
OpenShift Container Platform components are primarily written in Go
(golang). The golang.org/x/text contains text-related packages which are
used for
text operations, such as character encodings, text transformations, and
locale-specific text handling.
Kibana is one of the major components of OpenShift Container Platform
cluster logging. It is a browser-based console interface to query,
discover, and visualize
the log data.
Security Fix(es):
* golang.org/x/text: possibility to trigger an infinite loop in
encoding/unicode could lead to crash (CVE-2020-14040)
* kibana: X-Frame-Option not set by default might lead to clickjacking
(CVE-2020-10743)
