Multicluster Engine for Kubernetes 2.2.3 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.

Security fix(es):

CVE-2022-25881 http-cache-semantics: Regular Expression Denial of Service (ReDoS) vulnerability
CVE-2023-29017 vm2: Sandbox Escape
CVE-2023-29199 vm2: Sandbox Escape
CVE-2023-30547 vm2: Sandbox Escape when exception sanitization
