"value": "In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection."

"value": "En nghttp2 versiones anteriores a 1.41.0, la carga \u00fatil de la trama HTTP/2 SETTINGS demasiado grande causa una denegaci\u00f3n de servicio. El ataque de prueba de concepto involucra a un cliente malicioso que construye una trama SETTINGS con una longitud de 14,400 bytes (2400 entradas de configuraciones individuales) una y otra vez. El ataque causa que la CPU se aumente al 100%. nghttp2 versi\u00f3n v1.41.0 corrige esta vulnerabilidad. Existe una soluci\u00f3n alternativa a esta vulnerabilidad. Implemente la funci\u00f3n nghttp2_on_frame_recv_callback callback, y si la trama es recibida es la trama SETTINGS y el n\u00famero de entradas de configuraci\u00f3n es grande (por ejemplo, mayor a 32), luego desconecte la conexi\u00f3n"
