✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Workaround: Deploy reverse-proxy rate limiting and request timeout thresholds to drop abnormally slow or complex incoming network requests before they reach the backend .NET service. Enforce CPU and memory cgroup limits on application containers to isolate resource exhaustion to the impacted service. Workaround: Deploy reverse-proxy rate limiting, connection thresholds, and strict request timeouts to drop abusive network requests before they reach the backend .NET service. Enforce CPU and memory cgroup limits on application containers to isolate resource exhaustion.
