Technical Summary
This advisory covers security updates for Red Hat OpenShift Container Platform versions 4.17 and 4.18. The key vulnerabilities fixed include CVE-2024-7128, an unauthenticated data exposure in the openshift-console component, and use-after-free vulnerabilities in libxslt (CVE-2024-55549 and CVE-2025-24855). Additionally, a denial of service vulnerability in go-jose (CVE-2025-27144) is addressed. The updates are delivered as container image updates for OpenShift Container Platform 4.17.29 and 4.18.12. The vendor rates the security impact as Moderate to Important depending on the release. Detailed upgrade instructions and image digests are provided by Red Hat. No known exploits in the wild have been reported at this time.
Potential Impact
The unauthenticated data exposure vulnerability (CVE-2024-7128) could allow an attacker to access sensitive information without authentication. Use-after-free vulnerabilities in libxslt could lead to memory corruption, potentially causing crashes or other unintended behavior. The denial of service vulnerability in go-jose could allow attackers to disrupt service availability. Overall, these vulnerabilities pose a moderate security risk if left unpatched.
Mitigation Recommendations
Red Hat has released fixed container images for OpenShift Container Platform versions 4.17.29 and 4.18.12 that address these vulnerabilities. Users should upgrade to these versions as soon as they are available in their release channels. Upgrades can be performed using the OpenShift CLI (oc) or the web console following the vendor's documented procedures. No additional mitigations are specified beyond applying these updates.
