A NULL pointer dereference was detected during fuzzing of the analysis engine, allowing malicious clients to DoS the analysis engine. The bug occurs when `analysisd` receives a syscollector message with the `hotfix` `msg_type` but lacking a `timestamp`. It uses `cJSON_GetObjectItem()` to get the `timestamp` object item and dereferences it without checking for a `NULL` value. A malicious client can DoS the analysis engine. This vulnerability is fixed in 4.7.1."}, {"lang": "es", "value": "Wazuh es una plataforma gratuita y de c\u00f3digo abierto que se utiliza para la prevenci\u00f3n, detecci\u00f3n y respuesta a amenazas.
