Multicluster Engine for Kubernetes 2.6.3 General Availability release images and updated container images.

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 links in the References section.

Description

Multicluster engine for Kubernetes v2.6.3 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):

nodejs/elliptic: EDDSA signature malleability occurs because there is a missing signature length check, and thus zero-valued bytes can be removed or appended (CVE-2024-42459)
nodejs/elliptic: ECDSA signature malleability occurs because there is a missing check for whether the leading bit of r and s is zero (CVE-2024-42460)
nodejs/elliptic: ECDSA implementation malleability due to BER-enconded signatures being allowed (CVE-2024-42461)
