Changelog
*Sourced from [waitress's changelog](https://github.com/Pylons/waitress/blob/master/CHANGES.txt).* > 1.4.0 (2019-12-20) > ------------------ > > Bugfixes > ~~~~~~~~ > > - Waitress used to slam the door shut on HTTP pipelined requests without > setting the ``Connection: close`` header as appropriate in the response. This > is of course not very friendly. Waitress now explicitly sets the header when > responding with an internally generated error such as 400 Bad Request or 500 > Internal Server Error to notify the remote client that it will be closing the > connection after the response is sent. > > - Waitress no longer allows any spaces to exist between the header field-name > and the colon. While waitress did not strip the space and thereby was not > vulnerable to any potential header field-name confusion, it should have sent > back a 400 Bad Request. See [Pylons/waitress#273](https://github-redirect.dependabot.com/Pylons/waitress/issues/273) > > Security Fixes > ~~~~~~~~~~~~~~ > > - Waitress implemented a "MAY" part of the RFC7230 > (https://tools.ietf.org/html/rfc7230#section-3.5) which states: > > Although the line terminator for the start-line and header fields is > the sequence CRLF, a recipient MAY recognize a single LF as a line > terminator and ignore any preceding CR. > > Unfortunately if a front-end server does not parse header fields with an LF > the same way as it does those with a CRLF it can lead to the front-end and > the back-end server parsing the same HTTP message in two different ways. This > can lead to a potential for HTTP request smuggling/splitting whereby Waitress > may see two requests while the front-end server only sees a single HTTP > message. > > For more information I can highly recommend the blog post by ZeddYu Lu > https://blog.zeddyu.info/2019/12/08/HTTP-Smuggling-en/ > > - Waitress used to treat LF the same as CRLF in ``Transfer-Encoding: chunked`` > requests, while the maintainer doesn't believe this could lead to a security > issue, this is no longer supported and all chunks are now validated to be > properly framed with CRLF as required by RFC7230. > > - Waitress now validates that the ``Transfer-Encoding`` header contains only > transfer codes that it is able to decode. At the moment that includes the > only valid header value being ``chunked``. > > That means that if the following header is sent: > > ``Transfer-Encoding: gzip, chunked`` > ... (truncated)Commits
