Red Hat Security Advisory: Red Hat Advanced Cluster Management 2.11.3 bug fixes and container updates
Red Hat Advanced Cluster Management for Kubernetes 2.11.3 images 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. See the following Release Notes documentation, which will be updated shortly for this release, for additional details about this release: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.6/html/release_notes/ 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) CVE-2024-48949 Missing Validation in Elliptic's EDDSA Signature Verification
AI Analysis
Technical Summary
This advisory covers multiple vulnerabilities in the nodejs/elliptic cryptographic library used within Red Hat Advanced Cluster Management for Kubernetes. Specifically, CVE-2024-42459 describes EDDSA signature malleability caused by a missing signature length check allowing zero-valued bytes to be removed or appended. CVE-2024-42460 involves ECDSA signature malleability due to missing checks on the leading bit of the r and s values. CVE-2024-42461 relates to ECDSA malleability from allowing BER-encoded signatures. CVE-2024-48949 concerns missing validation in EDDSA signature verification. These issues could affect the integrity of cryptographic signatures. The vulnerabilities are fixed in version 2.11.3 of Red Hat Advanced Cluster Management for Kubernetes.
Potential Impact
The vulnerabilities involve signature malleability and missing validation in cryptographic signature verification, which could potentially allow attackers to manipulate or forge signatures under certain conditions. This could undermine the integrity guarantees of cryptographic operations within the affected product. No known exploits in the wild have been reported. The security impact is rated as Important by Red Hat Product Security.
Mitigation Recommendations
Red Hat has released version 2.11.3 of Advanced Cluster Management for Kubernetes containing fixes for these vulnerabilities. Users should update to version 2.11.3 or later to remediate these issues. Before applying this update, ensure all previously released errata relevant to your system have been applied.
