Descriptions
The Eclipse Mosquitto broker up to version 1.4.15 does not reject strings that are not valid UTF-8. A malicious client could cause other clients that do reject invalid UTF-8 strings to disconnect themselves from the broker by sending a topic string which is not valid UTF-8, and so cause a denial of service for the clients.
El broker Eclipse Mosquitto hasta la versión 1.4.15 no rechaza strings que no son UTF-8 válidos. Un cliente malicioso podría provocar que otros clientes que sí rechazan strings UTF-8 no válidos se desconecten del broker enviando un string topic que no es un UTF-8 válido, provocando así una denegación de servicio (DoS) a los clientes.
