+	 <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>
