Summary
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions 7.0.10 and below and 8.0.0-beta1 through 8.0.0-rc1, mishandling of data on HTTP2 stream 0 can lead to uncontrolled memory usage, leading to loss of visibility. Workarounds include disabling the HTTP/2 parser, and using a signature like drop http2 any any -> any any (frame:http2.hdr; byte_test:1,=,0,3; byte_test:4,=,0,5; sid: 1;) where the first byte test tests the HTTP2 frame type DATA and the second tests the stream id 0. This is fixed in versions 7.0.11 and 8.0.0.

"value": "Suricata es un motor de red IDS, IPS y NSM desarrollado por la OISF (Open Information Security Foundation) y la comunidad Suricata. En las versiones 7.0.10 y anteriores, y de la 8.0.0-beta1 a la 8.0.0-rc1, la gesti\u00f3n incorrecta de datos en el flujo HTTP2 0 puede provocar un uso incontrolado de memoria, lo que conlleva p\u00e9rdida de visibilidad. Las soluciones alternativas incluyen deshabilitar el analizador HTTP/2 y usar una firma como `drop http2 any any -\u0026gt; any any (frame:http2.hdr; byte_test:1,=,0,3; byte_test:4,=,0,5; sid: 1;\u0027\u0027), donde la primera prueba de bytes verifica el tipo de trama HTTP2 `DATA\u0027\u0027 y la segunda el ID de flujo 0. Esto se ha corregido en las versiones 7.0.11 y 8.0.0."
