If someone is already invoking #!/bin/bash from a cgi, then they are already doing it wrong (bash has massive bloat/overhead for a CGI

You sure you don't have *any* cgi's that do something like system("mail -s 'cgi program xxyz hit fatal error' webadmin@localhost"); because all it takes is finding a way to force the fatal error while you send a crafted User-Agent: header....
That won't automatically invoke bash on Debian/Ubuntu....unless someone intentionally changed default shells.... -Jim P.
