Vulnerability from variot

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. Multiple HTTP/2 implementations are vulnerable to a variety of denial-of-service (DoS) attacks. HTTP/2 is the second version of the hypertext transfer protocol, which is mainly used to ensure the communication between the client and the server. A resource management error vulnerability exists in HTTP/2. An attacker could exploit this vulnerability to cause a denial of service. it exists 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). Description:
