Como tal, escribir en este directorio utilizando API que no establecen explícitamente los permisos de archivo/directorio puede dar lugar a la divulgación de información. Es de destacar que esto no afecta a los sistemas operativos MacOS modernos. El método File.createTempFile en sistemas tipo Unix crea un archivo con un nombre predefinido (fácilmente identificable) y, de forma predeterminada, creará este archivo con los permisos -rw-r--r--. Por lo tanto, si se escribe información confidencial en este archivo, otros usuarios locales pueden leer esta información.
