| summary: Denial of service from HTTP/2 Rapid Reset in google.golang.org/grpc |
| description: |- |
| An attacker can send HTTP/2 requests, cancel them, and send subsequent requests. |
| This is valid by the HTTP/2 protocol, but would cause the gRPC-Go server to |
| launch more concurrent method handlers than the configured maximum stream limit, |
| grpc.MaxConcurrentStreams. This results in a denial of service due to resource |
| consumption. |
