In other words, Nautilus provides no UI indication that a file actually has the potentially unsafe .desktop extension; instead, the UI only shows the .pdf extension. One (slightly) mitigating factor is that an attack requires the .desktop file to have execute permission. The solution is to ask the user to confirm that the file is supposed to be treated as a .desktop file, and then remember the user's answer in the metadata::trusted field."}, {"lang": "es", "value": "GNOME Nautilus en versiones anteriores a la 3.23.90 permite que los atacantes suplanten un tipo de archivo mediante la extensi\u00f3n de archivo .desktop, tal y como se ve en un ataque en el cual el nombre de un archivo .desktop acaba en .pdf, pero el campo Exec de este archivo lanza un comando \"sh-c\" malicioso. En otras palabras, Nautilus no proporciona ninguna indicaci\u00f3n en la interfaz de usuario sobre si un archivo tiene realmente la extensi\u00f3n .desktop. En lugar de eso, la interfaz de usuario s\u00f3lo muestra la extensi\u00f3n .pdf. Un factor de mitigaci\u00f3n (leve) es que un ataque requiere que el archivo .desktop tenga permisos de ejecuci\u00f3n.
