      "value": "Suricata is a network IDS, IPS and NSM engine. Prior to versions 8.0.3 and 7.0.14, crafted DCERPC traffic can cause Suricata to expand a buffer w/o limits, leading to memory exhaustion and the process getting killed. While reported for DCERPC over UDP, it is believed that DCERPC over TCP and SMB are also vulnerable. DCERPC/TCP in the default configuration should not be vulnerable as the default stream depth is limited to 1MiB. Versions 8.0.3 and 7.0.14 contain a patch. Some workarounds are available. For DCERPC/UDP, disable the parser. For DCERPC/TCP, the `stream.reassembly.depth` setting will limit the amount of data that can be buffered. For DCERPC/SMB, the `stream.reassembly.depth` can be used as well, but is set to unlimited by default. Imposing a limit here may lead to loss of visibility in SMB."

      "value": "Suricata es un motor de IDS, IPS y NSM de red. Antes de las versiones 8.0.3 y 7.0.14, el tráfico DCERPC manipulado puede hacer que Suricata expanda un búfer sin límites, lo que lleva al agotamiento de la memoria y a la terminación del proceso. Aunque se informó para DCERPC sobre UDP, se cree que DCERPC sobre TCP y SMB también son vulnerables. DCERPC/TCP en la configuración predeterminada no debería ser vulnerable, ya que la profundidad de flujo predeterminada está limitada a 1 MiB. Las versiones 8.0.3 y 7.0.14 contienen un parche. Algunas soluciones alternativas están disponibles. Para DCERPC/UDP, deshabilite el analizador. Para DCERPC/TCP, la configuración 'stream.reassembly.depth' limitará la cantidad de datos que se pueden almacenar en búfer. Para DCERPC/SMB, también se puede usar 'stream.reassembly.depth', pero está configurado como ilimitado por defecto. Imponer un límite aquí puede llevar a la pérdida de visibilidad en SMB."
