Eventlet is a concurrent networking library for Python. Prior to version0.40.3, the Eventlet WSGI parser is vulnerable to HTTP Request Smugglingdue to improper handling of HTTP trailer sections. This vulnerability couldenable attackers to, bypass front-end security controls, launch targetedattacks against active site users, and poison web caches. This problem hasbeen patched in Eventlet 0.40.3 by dropping trailers which is a breakingchange if a backend behind eventlet.wsgi proxy requires trailers. Aworkaround involves not using eventlet.wsgi facing untrusted clients.
