Descriptions
In Splunk Enterprise versions below 8.2.9, 8.1.12, and 9.0.2, sending a malformed file through the Splunk-to-Splunk (S2S) or HTTP Event Collector (HEC) protocols to an indexer results in a blockage or denial-of-service preventing further indexing.
En las versiones de Splunk Enterprise inferiores a 8.2.9, 8.1.12 y 9.0.2, el envío de un archivo con formato incorrecto a través de los protocolos Splunk-to-Splunk (S2S) o HTTP Event Collector (HEC) a un indexador provoca un bloqueo o denegación fuera de servicio evitando una mayor indexación.
