... unless you have an insecure NFS environment (even if root is mapped
to nobody, anybody can access anybody else's home network directory
by locally creating a user with the same UID).
This method can be used to gain the target's UID on their workstation
if network logins are allowed and setuid on the network volumes is not
disabled, or if there's a security hole on the target system, or ...
There are many places out there who have neither of these security
problems plugged. :-/ Thus I agree that while panic is inappropriate,
we shouldn't trivialize the problem either. It _does_ allow some people
to gain access to secret keys who couldn't get it so otherwise.
