In legacy mode, messages featuring a transfer-encoding header missing the &#34;chunked&#34; value were not being correctly rejected. The impact was limited but if combined with the &#34;http-reuse always&#34; setting, it could be used to help construct an HTTP request smuggling attack against a vulnerable component employing a lenient parser that would ignore the content-length header as soon as it saw a transfer-encoding one (even if not entirely valid according to the specification).</p> <p>A flaw was found in HAProxy before 2.0.6.
