Twisted developers reports :

All HTTP clients in twisted.web.client now raise a ValueError when called with a method and/or URL that contain invalid characters. This mitigates CVE-2019-12387. Thanks to Alex Brasetvik for reporting this vulnerability.

The HTTP/2 server implementation now enforces TCP flow control on control frame messages and times out clients that send invalid data without reading responses. This closes CVE-2019-9512 (Ping Flood), CVE-2019-9514 (Reset Flood), and CVE-2019-9515 (Settings Flood).
Thanks to Jonathan Looney and Piotr Sikora.

twisted.web.http was subject to several request smuggling attacks.
Requests with multiple Content-Length headers were allowed (CVE-2020-10108, thanks to Jake Miller from Bishop Fox and ZeddYu Lu for reporting this) and now fail with a 400; requests with a Content-Length header and a Transfer-Encoding header honored the first header (CVE-2020-10109, thanks to Jake Miller from Bishop Fox for reporting this) and now fail with a 400; requests whose Transfer-Encoding header had a value other than 'chunked' and 'identity' (thanks to ZeddYu Lu) were allowed and now fail with a 400.

Security fix for CVE-2020-10108 (#1813439, #1813441) Security fix for CVE-2020-10109 (#1813447, #1813449)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4308-1 advisory.

    it was discovered that Twisted incorrectly validated or sanitized certain URIs or HTTP methods. A remote     attacker could use this issue to inject invalid characters and possibly perform header injection attacks.
    (CVE-2019-12387)

    It was discovered that Twisted incorrectly verified XMPP TLS certificates. A remote attacker could     possibly use this issue to perform a machine-in-the-middle attack and obtain sensitive information.
    (CVE-2019-12855)

    It was discovered that Twisted incorrectly handled HTTP/2 connections. A remote attacker could possibly     use this issue to cause Twisted to hang or consume resources, leading to a denial of service. This issue     only affected Ubuntu 18.04 LTS and Ubuntu 19.10.
