[Security Fix]
- Go の HTTP/2 クライアント機能には、接続先のサーバーに対して
意図しないリソースを消費させてしまう問題があるため、リモート
の攻撃者により、細工された Go アプリケーションからの新規の多重
ストリームのリクエストと RST_STREAM フレームによるリクエスト
のキャンセルの送信を介して、サービス拒否攻撃 (リソース枯渇) を
可能とする脆弱性が存在します。(CVE-2023-39325)
- HTTP/2 プロトコルには、意図しないリソースの消費に至る問題
があるため、リモートの攻撃者により、新規の多重ストリームの

CVE:
CVE-2023-39325
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.

CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
