"details": "it was discovered that Twisted incorrectly validated or sanitized certain\nURIs or HTTP methods. A remote attacker could use this issue to inject\ninvalid characters and possibly perform header injection attacks.\n(CVE-2019-12387)\n\nIt was discovered that Twisted incorrectly verified XMPP TLS certificates.\nA remote attacker could possibly use this issue to perform a\nmachine-in-the-middle attack and obtain sensitive information. (CVE-2019-12855)\n\nIt was discovered that Twisted incorrectly handled HTTP/2 connections. A\nremote attacker could possibly use this issue to cause Twisted to hang or\nconsume resources, leading to a denial of service. This issue only affected\nUbuntu 18.04 LTS and Ubuntu 19.10. (CVE-2019-9512, CVE-2019-9514,\nCVE-2019-9515)\n\nJake Miller and ZeddYu Lu discovered that Twisted incorrectly handled\ncertain content-length headers. A remote attacker could possibly use this\nissue to perform HTTP request splitting attacks. (CVE-2020-10108,\nCVE-2020-10109)\n",
