CVE-2019-18277 (https://nvd.nist.gov/vuln/detail/CVE-2019-18277):
  A flaw was found in haproxy before version 2.0.6. In legacy mode, messages
  featuring a transfer-encoding header missing the "chunked" value was not
  being correctly rejected. The impact was limited but if combined with
  "http-reuse always", it could be used as an help to construct a content
  smuggling attack against a vulnerable component employing a lenient parser
  which would ignore the content-length header as soon as it sees a
  transfer-encoding one, without even parsing it.
