GoogHOle Exploits GMail, Picasa and 200K Other Sites

Giorgio Maone writes "Multiple Google-targeted exploits disclosed in the past 3 days could compromise your GMail account, steal your pictures from Picasa or impersonate you on almost 200,000 big sites which outsourced their search engines (vulnerabilities included in the price). If even Google, a very reactive company when web security matters, does face this kind of problems, how serious is the threat and what can you do, as a "normal" web user, to protect yourself?"

Good coding practices aside, programmers are human and make errors. You do your best to catch as many as you can, and that's all you can do. When you're a "consumer" of code, you look for an organization that seems to be doing this and use their stuff. There's no complete, proactive solution to bugs.
