Red Hat Security Advisory: OpenShift Container Platform 4.18.4 security update
Red Hat OpenShift Container Platform 4. 18. 4 includes security updates addressing multiple vulnerabilities across various components such as Buildah, golang. org/x/net/html, the Linux kernel HID core, mholt/archiver, golang-protobuf, and distribution token authentication. These fixes resolve issues including arbitrary directory mounts, path traversal, infinite loops during JSON unmarshaling, and token authentication weaknesses. Users of OpenShift Container Platform 4. 18 are advised to upgrade to the updated packages and container images to mitigate these vulnerabilities.
AI Analysis
Technical Summary
This advisory covers security updates in Red Hat OpenShift Container Platform 4.18.4 that fix six distinct vulnerabilities: CVE-2024-9675 (Buildah arbitrary directory mount), CVE-2024-45338 (non-linear parsing in golang.org/x/net/html), CVE-2024-50302 (kernel HID core zero-initialization), CVE-2024-0406 (path traversal in mholt/archiver), CVE-2024-24786 (infinite loop in golang-protobuf protojson.Unmarshal), and CVE-2025-24976 (token authentication allowing injection of untrusted signing keys in JWT). The update includes new container images and RPM packages. The advisory emphasizes upgrading OpenShift Container Platform 4.18 clusters using the OpenShift CLI or web console to apply these fixes.
Potential Impact
The vulnerabilities fixed in this update could allow attackers to perform unauthorized directory mounts, path traversal attacks, cause infinite loops during JSON unmarshaling, and inject untrusted signing keys into JWT tokens used for authentication. These issues pose a high security risk by potentially enabling privilege escalation, denial of service, or authentication bypass within affected OpenShift Container Platform deployments.
Mitigation Recommendations
Red Hat has released updated container images and RPM packages as part of OpenShift Container Platform 4.18.4 that address these vulnerabilities. Users should upgrade their OpenShift 4.18 clusters promptly using the OpenShift CLI (oc) or web console following the official upgrade instructions provided by Red Hat. No alternative mitigations are indicated; applying the official update is required to remediate these issues.
