Title
Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service
Summary

The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
