this is a great post on how SELinux can help overall in situations like
this as well.

the other thing that is important to note here is that there is -lots-
of software out there that uses system() calls to do things, every one
of those is potentially at risk here; nagios / gitweb etc are just a tip
of the iceberg. There is plenty of desktop / app grade software that
does this as well.

So, although I agree that bash for cgi-scripts is just completely
whacked out, in many cases the issue is being inherited from other code,
that does the system shell out.

btw, sky hd+ box's running linux... also exploiteable.
