Firefox Exploit
Robert McLaws FunWithCoding.NET has nice commentary on the Firefox exploit.
The lesson for me, of course, is that vulnerabilities are vulnerabilities and they exist or don't exist and the type of software (Open Source or "closed-source") is largely irrelevant.
Yes, Windows applications requiring Admin access to run is wrong. Yes, IE and Windows itself has been traditionally a very vulnerable platform. Yes, yes, yes.
However, I am definitely amused by the ignorance of the Open Source supporters quoted in that commentary. I’m a Firefox user but I realize that it’s just software and it’s made by humans and it’s still vulnerable.
