At last, we have the final updates for 2020 from Microsoft. For anyone keeping count, we ended up with 1,250 CVEs (Common Vulnerabilities and Exposures) for the year. That’s almost 50% more than the 800 we had to deal with in 2019. Given the way we get updates delivered in a cumulative fashion, I don’t think of it as about the number of vulnerabilities; I think more about how many times I had to deal with post-release issues in 2020. I’ll recap the year’s major patching issues later this month. For now, I’ll summarize the issues to watch out for in December.
