NIST has a nice database that gives you all of the references for a particular vuln, it can be searched using the CVE number. SANS has a nice explanation of different risk levels that can be helpful in coming up with the actual risk on a given network. There are so many variables dependent on the environment of the host that you have to determine severity seperately for each network you evaluate.

We have found that we can only use other people's severity ratings as a
guide.  We have to rank them ourselves based on our applications and
architectures. We have a committee that meets weekly to review new *nix
vulnerabilities. (Our Microsoft folks meet just after Microsoft's security
announcements, usually on Black Tuesday.)

While nothing is perfect, we tend to use CVE ( cve.mitre.org ) for
information on each vulnerability (except for Microsoft and some other
vendor-specific vulnerabilities.)

Toto, I don't think we're in the mainframe world any more.
