Vulnerability Title
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service
Source: CVE Program / CVE List V5
Vulnerability Description
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
