But for many vulnerabilities no accommodations are necessary. Doyle said, "Code developed by iSight Partners Labs that exploited the recent Adobe printf vulnerability successfully triggered in both the IE and FF Adobe plug-ins, as well as Adobe reader and Adobe Acrobat."
It's not exactly the same thing, but I think it's worth mentioning that many social engineering tricks unrelated to vulnerabilities in any program are just as applicable to users of any browser. One popular trick these days is the fake news or some other content site pitched through spam. This example used supposed video of U.S. soldiers fighting in Iran. This one, from the day after the election, supposedly led to election results. In both cases they led to a Trojan horse program.
Often users are told they have to update their Flash viewer or some other viewer program to view the content, and are led to a download for that. Of course they often do carry out the download. Tip: If you want to update Flash, go to the Adobe site to do so.
Another factor that often comes up in these discussions is the difference in user bases for the browsers. IE is the great default, the browser for which any respectable exploit must work, because it has overwhelming market share. The only other browser with noticeable market share is Firefox; you hear numbers up to maybe 20 percent.
We're just stereotyping here, but it makes sense that Firefox users are more likely to be technically sophisticated and appreciative of security concerns. Such users are more likely to update their software religiously, more likely to recognize a scam site when they see it, less likely to fall for a fake error message. But these people push other, less sophisticated users to run Firefox as well; with browser share numbers of 20 percent, clearly there are a lot of novices running Firefox. So perhaps the percentage of users being exploited through third-party controls is larger for IE, but it should be above zero and rising for Firefox.
There are also tools to help Firefox users protect themselves, such as NoScript. I get in fights every time I say this, but I think it's not practical to use NoScript for everyday browsing, especially for a novice. But that's secondary to the main issue. Most Firefox users aren't using NoScript.
With Microsoft and Adobe both doing a better job of fighting vulnerabilities in their own products, it's not surprising, as the Microsoft Security Intelligence Report also finds, that vulnerabilities in software across the industry are declining. This is why social engineering and malware are becoming the real problems. But in the meantime, it makes sense that some of our longstanding biases about product security are not as correct as they might have been at one time.
