Null-Prefix SSL Attacks Enabled In New sslsniff
An anonymous reader writes "Moxie Marlinspike, who recently published new attacks on SSL at Defcon 17, seems to have released the new version of sslsniff which supports these attacks. While the release appears to coincide with a patch from Mozilla, every product that uses the Microsoft CryptoAPI is still vulnerable, including Internet Explorer and Outlook. The new version of sslsniff also supports built-in modes for hijacking software auto-updates that depend on SSL, and apparently includes techniques for defeating OCSP as well — making the elimination of existing null-prefix certificates difficult."
You're absolutely right. If this guy didn't inform anyone except Mozilla, he's bringing browsers wars to a new low, by being willing to expose a majority of web users involved in e-commerce and other "secure" online access to his vulnerability for whatever the lead time of patching is, but exempting users of his favorite browser. IF that's what he did, that's ridiculous, childish, and petty.
What about all the other vendors of SSL dependent software? SSL based VPNs like OpenVPN for example. No love for them either? Just Mozilla?
It shows how people like Dan K are smart enough to recognize major vulnerabilities that can potentially affect massive amounts of service/traffic/commerce need to be handled differently. It doesn't reduce the respect you gain as a security researcher for finding such a major flaw to give vendors notification in a reasonable time period before publication. I'm all for full disclosure as a means of punishing companies that don't respond, but for larger vulnerabilities I think notification and a deadline are the way to go.
