Security Bulletin
Summary
Red Hat OpenShift on IBM Cloud is affected by a security vulnerability that may allow a malicious user to trick cri-o into restoring a pod that doesn't have (CVE-2024-8676)
Vulnerability Details
Description: A vulnerability was found in CRI-O, where it can be requested to take a checkpoint archive of a container and later be asked to restore it. When it does that restoration, it attempts to restore the mounts from the restore archive instead of the pod request. As a result, the validations run on the pod spec, verifying that the pod has access to the mounts it specifies are not applicable to a restored container. This flaw allows a malicious user to trick CRI-O into restoring a pod that doesn't have access to host mounts. The user needs access to the kubelet or cri-o socket to call the restore endpoint and trigger the restore.

Remediation/Fixes
Updates for Red Hat OpenShift on IBM Cloud cluster worker nodes at versions 4.15 or later are available that fix this vulnerability. Customers must update worker nodes created before the fix was available to address the vulnerability. For details on updating worker nodes, see either the classic or VPC documentation, as appropriate. To verify your cluster worker nodes have been updated, use the following IBM Cloud CLI command to confirm the currently running versions:
ibmcloud oc workers --cluster <cluster name or ID>
If the versions are at one of the following patch levels or later, the cluster worker nodes have the fix:
Customers running Red Hat OpenShift on IBM Cloud Service clusters at version 4.13 must upgrade to version 4.14. Please review the documentation before starting an upgrade since additional actions may be required.
Customers running Red Hat OpenShift on IBM Cloud Service clusters at version 4.12 must create a new cluster and deploy their apps to the new cluster.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
