Описание
A client may issue HTTP/2 requests to a Jetty server that result in blocking writes that are never unblocked, eventually causing all threads to be blocked and the whole server to become unresponsive.
This is caused by a race condition in the server when handling RST_STREAM frames and GOAWAY frames sent by the client.
The race condition "resets" the HTTP2Flusher.terminated, previously set to a non-null value, to the null value, allowing entries to be enqueued in the flusher that however will never be processed. These unprocessed entries are the ones that would unblock the write-blocked threads.
A flaw was found in Jetty. A remote attacker can exploit a race condition in the server's handling of HTTP/2 RST_STREAM and GOAWAY frames. This can lead to blocking writes that are never unblocked, causing all server threads to become unresponsive. The primary impact is a Denial of Service (DoS) for the affected server.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
