+ <blockquote cite="https://www.sudo.ws/stable.html#1.9.5">
+ <p>A potential information leak in sudoedit that could be used to
+ test for the existence of directories not normally accessible to
+ the user in certain circumstances. When creating a new file,
+ sudoedit checks to make sure the parent directory of the new file
+ exists before running the editor. However, a race condition exists
+ if the invoking user can replace (or create) the parent directory.
+ If a symbolic link is created in place of the parent directory,
+ sudoedit will run the editor as long as the target of the link
+ exists.If the target of the link does not exist, an error message
+ will be displayed. The race condition can be used to test for the
+ existence of an arbitrary directory. However, it _cannot_ be used
+ to write to an arbitrary location.</p>
