A flaw was found in python-twisted. This vulnerability occurs due to the parsing of illegal constructs in the twisted.web.http module. The illegal constructs include '+/-' in the Content-Length header, '\n and \t' etc. Non-conformant parsing leads to a desync if requests pass through multiple HTTP parsers. This flaw allows a remote attacker to perform an HTTP request smuggling attack.
