I hate reading vulnerability bulletins. Talk about dense material. I sometimes find it difficult to follow explanations about systems I understand well, let alone those about systems I use but don't fully understand.

And I know I'm not alone. Network administrators who aren't immersed in security are just as disadvantaged.

Nearly all vendors and a few security researchers offer some sort of rating for new vulnerabilities. Although the ratings indicate how serious the author thinks the vulnerability is, you or someone in your organization will have to make that determination once the impact on your network is understood. This may sound obvious, but a threat to your DNS involving spoofing may seem low grade until you realize exactly how much trust we place in an untrustworthy system.
