I remember reading about something similar (if anybody knows something
more about it I would be happy to refresh my memory). Many admins did a
|mail from cron and they did it in a way that made it possible for
attackers to execute commands (mail has/had such a feature). The
conclusion was that we are using (though I was sure the problem was
eliminated long ago... guess I'm to young to know better :) programs not
designed to be secure in ways which require them to be secure (who cares
if your grep does a segfault? it's not suid!... but remember all those
maintenance scripts run from cron suid root? every third line does a
|grep... oops I did it again :).
