Descriptions

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, missing initialization of the random seed for "thash" leads to datasets having predictable hash table behavior. This can lead to dataset file loading to use excessive time to load, as well as runtime performance issues during traffic handling. This issue has been addressed in 7.0.7. As a workaround, avoid loading datasets from untrusted sources. Avoid dataset rules that track traffic in rules.

Suricata es un sistema de detección de intrusiones, un sistema de prevención de intrusiones y un motor de monitoreo de seguridad de red. Antes de la versión 7.0.7, la falta de inicialización de la semilla aleatoria para "thash" provocaba que los conjuntos de datos tuvieran un comportamiento de tabla hash predecible. Esto puede provocar que la carga de archivos de conjuntos de datos utilice un tiempo excesivo para cargarse, así como problemas de rendimiento en tiempo de ejecución durante el manejo del tráfico. Este problema se ha solucionado en la versión 7.0.7. Como workaround, evite cargar conjuntos de datos de fuentes no confiables. Evite las reglas de conjuntos de datos que rastrean el tráfico en las reglas.
