Synopsis
Critical: multicluster engine for Kubernetes v2.6.13 security update
Type/Severity
Security Advisory: Critical
Topic
Red Hat multicluster engine for Kubernetes v2.6 general availability release images, which provide security fixes, bug fixes, and updated container images.
Red Hat Product Security has rated this update as having a security impact of Critical.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE links in the References section.
Description
The multicluster engine for Kubernetes provides the foundational components
that are necessary for the centralized management of multiple
Kubernetes-based clusters across data centers, public clouds, and private
clouds.
You can use the engine to create new Red Hat OpenShift Container Platform
clusters or to bring existing Kubernetes-based clusters under management by
importing them. After the clusters are managed, you can use the APIs that
are provided by the engine to distribute configuration based on placement
policy.
Solution
For multicluster engine for Kubernetes, see the following documentation for
details on how to install the images:
