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.
