I browsed through the report, it's really a big difference between Vista/XP and RedHat. The difference between Vista and Ubuntu is smaller though.

As far as I know the report did not state how long it took Microsoft/RedHat/Ubuntu to correct the security errors once they were discovered.

It might be the case that Vista is more secure when it comes to vulnerabilities than the other operating systems in the report. Or fewer problems were discovered in Vista, but they are still lurking around.

Anyhow security isn't only about number of vulnerabilites during the first six months of use.
