libevent: libevent: Multiple HTTP Parser Bugs Enable Request Smuggling

A flaw was found in libevent. The evhttp parser in libevent's http.c component inconsistently handles HTTP Transfer-Encoding headers and chunked framing. This inconsistency allows an unauthenticated remote attacker to desynchronize request boundaries when libevent is used behind a proxy. Successf...
