NVD Description

Note: Versions mentioned in the description apply only to the upstream hey package and not the hey package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
