+Subject: [PATCH] http2: close connections when receiving too many headers
+
+Maintaining HPACK state requires that we parse and process
+all HEADERS and CONTINUATION frames on a connection.
+When a request's headers exceed MaxHeaderBytes, we don't
+allocate memory to store the excess headers but we do
+parse them. This permits an attacker to cause an HTTP/2
+endpoint to read arbitrary amounts of data, all associated
+with a request which is going to be rejected.
+
+Set a limit on the amount of excess header frames we
+will process before closing a connection.
+
+Thanks to Bartek Nowotarski for reporting this issue.
+
+Fixes CVE-2023-45288
+Fixes golang/go#65051
