>Description:
Man ftpd(8) suggests giving ~ftp/pub directory the permission
bits of 777 without adequately explaining potentially
unpleasant security implications of such a step. It is
suggested that

	
>How-To-Repeat:
$ man ftpd
[snip]
         ~ftp/pub  Make this directory mode 777 and owned by ``ftp''.
                   Guests can then place files which are to be accessible
                   via the anonymous account in this directory.
[snip]


	
>Fix:
Change the corresponding paragraph to, say:

        ~ftp/pub  Make this directory mode 700 and owned by ``ftp''.
                  Making this directory world-writable will
		  open you to a variety of DoS attacks as
		  well as being used for warez.
