Descriptions

In Suricata before 4.x, it was possible to trigger lots of redundant checks on the content of crafted network traffic with a certain signature, because of DetectEngineContentInspection in detect-engine-content-inspection.c. The search engine doesn't stop when it should after no match is found; instead, it stops only upon reaching inspection-recursion-limit (3000 by default).

En Suricata en versiones anteriores a las 4.x, era posible desencadenar numerosos chequeos redundantes en el contenido del trafico de red manipulado con una firma especifica a causa de DetectEngineContentInspection en detect-engine-content-inspection.c. El motor de busqueda no se detiene cuando debería despues de que no se encuentre ninguna coincidencia. En su lugar, solo se detiene al llegar al límite de recursión de inspecciónn (3000 por defecto).
