Changelog

Sourced from waitress's changelog.

1.4.1 (2019-12-24)

Security Fixes


- Waitress did not properly validate that the HTTP headers it received were
  properly formed, thereby potentially allowing a front-end server to treat a
  request different from Waitress. This could lead to HTTP request
  smuggling/splitting.

  Please see the security advisory for more information:
  https://github.com/Pylons/waitress/security/advisories/GHSA-m5ff-3wj3-8ph4

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
