RHSA-2021:0171 - Security Advisory

  • Overview

Synopsis

Moderate: OpenShift Container Platform 4.6.13 bug fix and security update

Type/Severity

Security Advisory: Moderate

Topic

Red Hat OpenShift Container Platform release 4.6.13 is now available with updates to packages and images that fix several bugs.

This release also includes a security update for Red Hat OpenShift Container Platform 4.6.

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

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):

  • kubernetes: Docker config secrets leaked when file is malformed and loglevel >= 4 (CVE-2020-8564)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

This advisory contains the container images for Red Hat OpenShift Container
Platform 4.6.13. See the following advisory for the RPM packages for this
release:

https://access.redhat.com/errata/RHSA-2021:0172

Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes:

https://docs.openshift.com/container-platform/4.6/release_notes/ocp-4-6-release-notes.html

This update fixes the following bug among others:

  • Previously, when the installation program checked to ensure the minimum 25GB disk space was available per node, the validation only checked the OpenStack flavor and not whether the separate root disk had been attached from dedicated storage. This caused clusters using a small flavor in combination with sufficient root disk space to be refused during installation. This has been fixed by considering the additional root disk space when validating the required disk space. Now you can successfully install a cluster with a combination of flavor disk space and root disk space. (BZ#1899161)

You may download the oc tool and use it to inspect release image metadata as follows:

(For x86_64 architecture)

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.6.13-x86_64

The image digest is sha256:8a9e40df2a19db4cc51dc8624d54163bef6e88b7d88cc0f577652ba25466e338

(For s390x architecture)

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.6.13-s390x

The image digest is sha256:3f195baabfd6490da256eec37c1dc3b3a5fad8370015828b3e0c12a2f20e2551

(For ppc64le architecture)

$ oc adm release info quay.io/openshift-release-dev/ocp-release:4.6.13-ppc64le

The image digest is sha256:242da710dde5851b07814df05e927d83cf1ca33a397f869ea99ceaf6e20a4054

All OpenShift Container Platform 4.6 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift Console or the CLI oc command. Instructions for upgrading a cluster are available
at https://docs.openshift.com/container-platform/4.6/updating/updating-cluster-between-minor.html#understanding-upgrade-channels_updating-cluster-between-minor.

Solution

For OpenShift Container Platform 4.6 see the following documentation, which
will be updated shortly for this release, for important instructions on how
to upgrade your cluster and fully apply this asynchronous errata update:
