CVE-2019-9514 Information
Description
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.
