Como tal, escribir en este directorio utilizando API que no establecen expl\u00edcitamente los permisos de archivo/directorio puede dar lugar a la divulgaci\u00f3n de informaci\u00f3n. Es de destacar que esto no afecta a los sistemas operativos MacOS modernos. El m\u00e9todo File.createTempFile en sistemas tipo Unix crea un archivo con un nombre predefinido (f\u00e1cilmente identificable) y, de forma predeterminada, crear\u00e1 este archivo con los permisos -rw-r--r--.
