More Microsoftie FUD
Another comparative "analysis" of security flaws in Windows and Red Hat. The result: Windows is better - the figures prove it. Well, yes, but let's look at those figures at little more. The giveaway is this paragraph:
Because of the nature of the Open Source model, there seems to be a higher tendency (unscientificly speaking) to just copy a piece of code and reuse it in another components. This means that if a piece of code turns out to be flawed, not only must it be fixed, but also that maintainers must find every place they might've reused that blob of code. A visual inspection showed me that many of these were the multiple vulnerabilities affecting firefox, mozilla and thunderbird. In a typical example, firefox packages were fixed, then mozilla packages were fixed 4 days later, then thunderbird was fixed 4 days after that.
Note that it says "In a typical example, firefox packages were fixed, then mozilla packages were fixed 4 days later". So one reason why Red Hat has more vulnerabilities is that it has far more packages included, many of which duplicate functions - like Firefox and Mozilla. The point is, you wouldn't install both Firefox and Mozilla: you'd choose one. So there's only one vulnerability that should be counted. Not only that, but Red Hat is penalised because it actually offers much more than Windows.
I don't know what the other vulnerabilities were, but I'd guess they involved similar over-counting - either through duplication, or simply because Red Hat offered extra packages. By all means compare Windows and Red Hat, but make it a fair comparison.
