Mac OS X Has More Vulnerabilities Than XP and Vista

Larry Dignan at ZDnet has posted a comparison of the numbers of vulnerabilities between Mac OS X and Windows, both XP and Vista, and while the numbers look like Microsoft has a big lead on security, it certainly does not mean that. It just says that Mac OS X has 5 times the flaws of XP and Vista every month in 2007.

Windows XP, Vista, and Mac OS X vulnerability stats for 2007
XP Vista XP + Vista Mac OS X
Total extremely critical 3 1 4 0
Total highly critical 19 12 23 234
Total moderately critical 2 1 3 2
Total less critical 3 1 4 7
Total flaws 34 20 44 243
Average flaws per month 2.83 1.67 3.67 20.25

Source: Mac versus Windows vulnerability stats for 2007

Now, before everyone does the Mac versus PC thing, this is just a comparison of the vulnerabilities and in no way does it say that Windows is more secure, now, if they did a comparison of the actual number of exploits taking advantage of the same vulnerabilities, I am sure the number would be severely tilted to Microsoft as they have the larger installed base. Plus, after reading some of the comments, it doesn’t take into account how many of these are actually from Apple for their software, as they distribute patches for the software that comes with their OS as well, lots of it being open source.
