El atacante debe ser un usuario autorizado del producto para realizar este ataque. Se recomienda a los usuarios que actualicen a la versi\u00f3n 4.0.0, que soluciona este problema. El problema ocurre cuando una aplicaci\u00f3n no utiliza un algoritmo de tiempo constante para validar una firma. El m\u00e9todo Arrays.equals() devuelve falso de inmediato cuando ve que uno de los bytes de entrada es diferente. Significa que el tiempo de comparaci\u00f3n depende del contenido de las matrices. Esta peque\u00f1a cosa puede permitir a un atacante falsificar una firma v\u00e1lida para un mensaje arbitrario byte a byte. Por lo tanto, podr\u00eda permitir que los usuarios malintencionados env\u00eden divisiones/trabajos con firmas seleccionadas a LLAP sin ejecutarse como un usuario privilegiado, lo que podr\u00eda conducir a un ataque DDoS.
