Original advisory details:
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)
Jake Miller and ZeddYu Lu discovered that Twisted incorrectly handled certain content-length headers. A remote attacker could possibly use this issue to perform HTTP request splitting attacks. (CVE-2020-10108, CVE-2020-10109)
