The only signal I would conclude from CVE data by itself, is that I bias towards a preference for companies that regularly publish CVEs. The ones that don't publish CVEs regularly are hiding, ignorant, or actually secure (and the first two are more likely).
You can't look at CVE in isolation.
Possibly if a product consistently has high cves over a long period of time that might tell you something about poor security practices over that period (or before it). It might also mean that their security is now quite good!
You have to interpret the data I'm afraid. I can't think of any useful statistical measures you could use to compare aggregate data across multiple products.
