Subject: Re: creating backups in temporary directories
Date: Sat, 08 Sep 2007 15:48:09 -0400	[thread overview]
Message-ID: <E1IU6Hp-0002hl-De@fencepost.gnu.org> (raw)
In-Reply-To: <jwvfy1q4axa.fsf-monnier+emacs@gnu.org> (message from Stefan Monnier on Fri, 07 Sep 2007 13:57:26 -0400)

    Worse yet: creating backup files in /tmp would be a security hole:
    some other user seeing you're currently editing /tmp/foo could create
    a symlink /tmp/foo~ to some interesting place and then when you save your
    file the backup could be placed at that interesting place chosen by
    the attacker.

Is that equally true for any directory that others can write?
