Top 25 vulnerability RSS feeds

One way to receive up-to-date reports about vulnerability issues is subscribing to vulnerability RSS feeds: they update on demand, they don’t rely on your mail subsystem and they don’t fill up your mailbox. The only drawback is that you could miss alerts if you don’t sync your feeds for a long time, but if you’re a IT security manager, you don’t have a life, so how could it happen anyways?
