I mentioned earlier that I’d update on this, and here we go. Our friends over in the Red Hat security team have posted POODLE – An SSL 3.0 Vulnerability (CVE-2014-3566), an article explaining the vulnerability in (not terribly technical) depth. If you’re curious (or worried!), check it out.
If you’re less curious, you may still want to skim Fedora Magazine’s earlier article. For desktop users, web browsing when you’re on an untrusted network is going to be the main risk, and adding this Mozilla-official no-restart-required extension to Firefox is a quick fix.
