        Agreed, but one could associate the ability as an unprivledged user to
read *other* users' environment variables with the finger(1) bug that allowed
users to read arbitraty files (or the sendmail uuencode bug, or ...).  The only
difference is that the target is not a file, it is an environment variable.

        There is a reason I make my shell's rc files mode 0700 and have a umask
of 077, and paranoia/security laziness are *not* why.  :)
