Some parsing functions in the affected product do not check the return value of malloc and the thread handling the message is forced to close, which may lead to a denial-of-service condition on the OPC UA Tunneller (versions prior to 6.3.0.8233).
Algunas funciones de análisis en el producto afectado no comprueban el valor de retorno de malloc y el subproceso que maneja el mensaje está obligado a cerrarse, lo que puede conllevar a una condición de denegación de servicio en el OPC UA Tunneller (versiones anteriores a 6.3.0.8233)
