✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Applications utilizing undici should implement an independent request deadline and ensure the response body is explicitly destroyed upon expiration. The bodyTimeout mechanism alone is insufficient to prevent resource exhaustion in this scenario. 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.
