      "value": "Eventlet is a concurrent networking library for Python. Prior to version 0.40.3, the Eventlet WSGI parser is vulnerable to HTTP Request Smuggling due to improper handling of HTTP trailer sections. This vulnerability could enable attackers to, bypass front-end security controls, launch targeted attacks against active site users, and poison web caches. This problem has been patched in Eventlet 0.40.3 by dropping trailers which is a breaking change if a backend behind eventlet.wsgi proxy requires trailers. A workaround involves not using eventlet.wsgi facing untrusted clients."

      "value": "Eventlet es una biblioteca de red concurrente para Python. Antes de la versión 0.40.3, el analizador WSGI de Eventlet es vulnerable a Contrabando de Solicitudes HTTP debido a un manejo inadecuado de las secciones de tráiler HTTP. Esta vulnerabilidad podría permitir a los atacantes eludir los controles de seguridad de front-end, lanzar ataques dirigidos contra usuarios activos del sitio y envenenar las cachés web. Este problema ha sido parcheado en Eventlet 0.40.3 eliminando los tráilers, lo cual es un cambio disruptivo si un backend detrás de un proxy eventlet.wsgi requiere tráilers. Una solución alternativa implica no usar eventlet.wsgi frente a clientes no confiables."
