Summary
Red Hat Security Advisory: Red Hat Advanced Cluster Management for Kubernetes v2.13.11 security update
Severity
Important
Notes
Topic: Red Hat Advanced Cluster Management for Kubernetes v2.13 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 Important. 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.
Details: Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console—with security policy built in. This advisory contains the container images for Red Hat Advanced Cluster Management for Kubernetes, which add new features and enhancements, bug fixes, and updated container images. See the following Release Notes documentation, which will be updated shortly for this release, for additional details about this release: https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.13/html-single/release_notes/index#acm-release-notes

A flaw was found in acm-operator-bundle. The build process for this component downloads and runs a script from a remote source without verifying its authenticity or integrity. This script gains access to sensitive credentials, such as GitHub access tokens and registry passwords, used in the build environment. A remote attacker could exploit this vulnerability to inject malicious code, leading to unauthorized access to build resources and potential compromise of the resulting operator bundle.
