Summary

In all Kubernetes versions prior to v1.11.8, v1.12.6, and v1.13.4, users that are authorized to make patch requests to the Kubernetes API Server can send a specially crafted patch of type "json-patch" (e.g. `kubectl patch --type json` or `"Content-Type: application/json-patch+json"`) that consumes excessive resources while processing, causing a Denial of Service on the API Server.

Patch / fix

  • go k8s.io/kubernetes 1.11.8, 1.12.6, 1.13.4
  • Kubernetes Kubernetes v1.11.8, v1.12.6, v1.13.4
