Summary
### Impact Rapidly creating and cancelling streams (HEADERS frame immediately followed by RST_STREAM) without bound cause denial of service. See https://www.cve.org/CVERecord?id=CVE-2023-44487 for details. ### Patches nghttp2 v1.57.0 mitigates this vulnerability by default. ### Workarounds If upgrading to nghttp2 v1.57.0 is not possible, implement `nghttp2_on_frame_recv_callback`, and check and count RST_STREAM frames. If excessive number of RST_STREAM are received, then take action, such as dropping connection silently, or call `nghttp2_submit_goaway` and gracefully terminate the connection. ### References The following commit mitigates this vulnerability: - https://github.com/nghttp2/nghttp2/commit/72b4af6143681f528f1d237b21a9a7aee1738832
