CVE-2019-9514 not yet assigned priority: Debian including 4 source packages (h2o, nodejs, rust-h2, trafficserver), 14 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 13, open 1.
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.
