RHSA-2020:3727 - Security Advisory

Topic

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.

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)
