✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Configure upstream reverse proxies or load balancers to strictly normalize HTTP headers and reject any incoming requests containing duplicate Transfer-Encoding headers before they reach the backend Tornado application worker. Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
