twisted - security update

Description

It was discovered that Twisted, a Python event-based framework for internet applications, is affected by HTTP request splitting vulnerabilities, and may expose sensitive data when following redirects. An attacker may bypass validation checks and retrieve credentials. * [CVE-2020-10108](https://security-tracker.debian.org/tracker/CVE-2020-10108) HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request. * [CVE-2020-10109](https://security-tracker.debian.org/tracker/CVE-2020-10109) HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request. * [CVE-2022-21712](https://security-tracker.debian.org/tracker/CVE-2022-21712) Twisted exposes cookies and authorization headers when following cross-origin redirects. This issue is present in the `twisted.web.RedirectAgent` and `twisted.web.BrowserLikeRedirectAgent` functions. For Debian 9 stretch, these problems have been fixed in version 16.6.0-2+deb9u1. We recommend that you upgrade your twisted packages.
