Se se\u00f1ala que crear un exploit que no solo cause un fallo es una tarea compleja, pero no se descarta esa posibilidad. La principal dificultad al desarrollar un exploit radica en que el atacante solo puede controlar cada segundo byte de la secuencia, mientras que el primer byte siempre toma el valor 0x04. Los sistemas de distribuci\u00f3n de software con verificaci\u00f3n mediante claves digitales est\u00e1n a salvo, ya que utilizan una lista de claves predefinida.<\/p>\n<p><noindex><a rel=\"nofollow\"
