      "value": "Memory Allocation with Excessive Size Value, Allocation of Resources Without Limits or Throttling, Missing Authentication for Critical Function vulnerability in Apache IoTDB.\nWhen pipe_air_gap_receiver_enabled=true, the IoTDB AirGap pipe receiver\naccepts raw TCP connections on port 9780 with no authentication. The\nreadLength method reads an attacker-controlled 32-bit integer from the\nsocket and readData passes it directly to new byte[length] with no\nupper-bound check. An unauthenticated attacker can cause the JVM to attempt\nan allocation of up to 2,147,483,647 bytes per connection, exhausting heap\nmemory and crashing or severely degrading the DataNode process.\n\n\nThis issue affects Apache IoTDB: from 1.0.0 before 2.0.10.\n\nUsers are recommended to upgrade to version 2.0.10, which fixes the issue."

      "value": "Asignación de memoria con valor de tamaño excesivo, Asignación de recursos sin límites o limitación, vulnerabilidad de autenticación faltante para función crítica en Apache IoTDB.\nCuando pipe_air_gap_receiver_enabled=true, el receptor de tubería AirGap de IoTDB acepta conexiones TCP sin procesar en el puerto 9780 sin autenticación. El método readLength lee un entero de 32 bits controlado por el atacante del socket y readData lo pasa directamente a new byte[length] sin verificación de límite superior. Un atacante no autenticado puede hacer que la JVM intente una asignación de hasta 2.147.483.647 bytes por conexión, agotando la memoria del montón y bloqueando o degradando gravemente el proceso DataNode.\n\nEste problema afecta a Apache IoTDB: desde 1.0.0 antes de 2.0.10.\n\nSe recomienda a los usuarios actualizar a la versión 2.0.10, que corrige el problema."
