The Mad, Mad Dash to Update Flash

An analysis of how quickly different browser users patch Adobe Flash vulnerabilities shows a marked variation among browser makers. The data suggest that Google Chrome and Mozilla Firefox users tend to get Flash updates relatively quickly, while many users on Microsoft’s Internet Explorer browser consistently lag behind.

The information comes from ThreatMetrix, a company that helps retailers and financial institutions detect and block patterns of online fraud. ThreatMetrix Chief Technology Officer Andreas Baumhof looked back over the past five months across 10,000+ sites the company serves, to see how quickly visitors were updating to the latest versions of Flash.

Baumhof measured the rates of update adoption for these six Flash patches:

Jan 14, 2014 – APSB14-02 Security updates available for Adobe Flash Player (2 critical vulnerabilities)

Feb 4, 2014 – APSB14-04 Security updates available for Adobe Flash Player (2 critical flaws, including 1 zero-day)

Feb 20, 2014 – APSB14-07 Security updates available for Adobe Flash Player (1 zero-day)

Mar 11, 2014 – APSB14-08 Security updates available for Adobe Flash Player (2 critical vulnerabilities)

Apr 8, 2014, – APSB14-09 Security updates available for Adobe Flash Player (4 critical vulnerabilities)

Apr 28, 2014 - APSB14-13 Security updates available for Adobe Flash Player (1 zero-day)

Overall, Google Chrome users were protected the fastest. According to Baumhof, Chrome usually takes just a few days to push the latest update out to 90 percent of users. Chrome pioneered auto-updates for Flash several years ago, with Firefox and newer versions of IE both following suit in recent years.

Interestingly, the data show that IE users tend to receive updates at a considerably slower clip (although there are a few times in which IE surpasses Firefox users in adoption of the latest Flash updates).  This probably has to do with the way Flash is updated on IE, and the legacy versions of IE that are still out there. Flash seems to have more of a seamless auto-update process on IE 10 and 11 on Windows 8 and above, and more of a manual one on earlier versions of the browser and operating system.

Another explanation for IE’s performance here is that it is commonly used in business environments, which tend to take a few days at least to test patches before rolling them out in a coordinated fashion across the enterprise along with the rest of the Patch Tuesday updates. Continue reading →

Mozilla Plugin Check Now Does Windows (Sort of)

Mozilla‘s Plugin Check Web site, which inspects Firefox browsers for outdated and insecure plugins, now checks other browsers — including Apple‘s Safari, Google‘s Chrome, Opera, and (to a far lesser extent) even Internet Explorer.

The Plugin Check site looks for a range of outdated plugins, and now works on Safari 4, Google Chrome  4 and up, Mozilla Firefox 3.0 and up, and Opera 10.5. This is a nice idea, and it works to some degree, but the page couldn’t locate version information for about seven of ten plugins I currently have in Firefox.

Similarly it detected version information for three out of nine of my plugins on my Macbook Pro’s Safari installation, although it helpfully informed me of an outdated Flash player on my Mac (doh!). It also detected version numbers for just two of 11 plugins apparently installed in my Google Chrome browser.

Mozilla’s Plugin Check also partially supports IE7 and IE8, although when I visited it with IE, I received an interesting result. I went there with a virgin install of IE8 that didn’t have any third party plugins installed. But rather than tell me I was secure  because it could detect no plugins at all, Mozilla’s site actually prompted me to install Adobe’s Flash Player (screen shot below), one of the most-attacked browser plugins of all.

It would be great to see this technology start to detect more plugins. In the meantime, if you’re running Windows and want help keeping up to date with the latest patches, I’d recommend Secunia‘s Personal Software Inspector, a program that periodically reminds you about insecure programs and plugins, and even includes links to download the latest patches.
