| summary: HTTP/2 rapid reset can cause excessive work in net/http |
| description: |- |
| A malicious HTTP/2 client which rapidly creates requests and immediately resets |
| them can cause excessive server resource consumption. While the total number of |
| requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting |
| an in-progress request allows the attacker to create a new request while the |
| existing one is still executing. |
| |
| With the fix applied, HTTP/2 servers now bound the number of simultaneously |
| executing handler goroutines to the stream concurrency limit |
| (MaxConcurrentStreams). New requests arriving when at the limit (which can only |
| happen after the client has reset an existing, in-flight request) will be queued |
| until a handler exits. If the request queue grows too large, the server will |
| terminate the connection. |
| |
| This issue is also fixed in golang.org/x/net/http2 for users manually |
| configuring HTTP/2. |
| |
| The default stream concurrency limit is 250 streams (requests) per HTTP/2 |
| connection. This value may be adjusted using the golang.org/x/net/http2 package; |
| see the Server.MaxConcurrentStreams setting and the ConfigureServer function. |
