CVE-2024-28182

nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream. There is no workaround for this vulnerability.

nghttp2 es una implementación del protocolo de transferencia de hipertexto versión 2 en C. La librería nghttp2 anterior a la versión 1.61.0 sigue leyendo el número ilimitado de tramas de CONTINUACIÓN HTTP/2 incluso después de que se restablece una secuencia para mantener sincronizado el contexto HPACK. Esto provoca un uso excesivo de la CPU para decodificar el flujo HPACK. nghttp2 v1.61.0 mitiga esta vulnerabilidad al limitar la cantidad de cuadros de CONTINUACIÓN que acepta por transmisión. No existe workaround para esta vulnerabilidad.
