(RHSA-2023:5421) Moderate: Multicluster Engine for Kubernetes 2.3.2 security updates and bug fixes

Multicluster Engine for Kubernetes 2.3.2 images

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.
