Software with the most vulnerabilities in 2015: Mac OS X, iOS, and Flash

Why is Mac OSX one item yet Windows is split up at every single version? Even Air seems weirdly split up.

Because the data are competely unsuitable for producing meaningful statistics:

This is completely meaningless since it doesn't take into account patches. I.e. It doesn't characterize the number of exploitable vulnerabilities on devices and still open to attack - just the number that were reported during the year.

The fact that there is still no jailbreak for the current version of iOS, whilst there are active million-node android botnets paints a different picture.

Here's my stock response to these vulnerability counting reports:
