the problem is not that the existence of a program that allows anybody
to become root, but, the real problem is preventing "any arbitrary" person
or program" from gaining access to the machine
- allow only certain ip# to log into your servers
and everybody should not have an acct on those servers

always use the latest kernel ... from kernel.org ...
and similarly with other important binaries from their
respective originating site
mta, apache, kernel, glib, make/gcc, bash, endless list
and watch out for the new dog that will bite because its
the newest and latest sources ( with unknown bugs ) vs the "old dog"
( older versions with known exploits )
roll the dice ... old buggs ... or new buggs .. snake eyes
