I'm not sure what the first paragraph in the article states. The part I'm having trouble with is: most discovered software flaws requiring security updates and notifications. Does that mean that Google Chrome fixed the most bugs, or were the most bugs found in Google Chrome?

If it was the former, Google is being shown in a positive light and they don't have any sort of "dubious distinction", and if it was the latter, then Google has an explanation for that. Lots of bugs are found in Chrome since Google pays developers a lot of money to find bugs in Chrome (not really sure about the others).
