Test Your Browser’s Patch Status

With new security updates from vendors like Adobe, Apple and Java coming out on a near-monthly basis, keeping your Web browser patched against the latest threats can be an arduous, worrisome chore. But a new browser plug-in from security firm Qualys makes it quick and painless to identify and patch outdated browser components.

Qualys Browser Check plug-inThe Qualys BrowserCheck plug-in works across multiple browsers — including Internet Explorer, Firefox, Chrome and Opera, on multiple operating systems. Install the plug-in, restart the browser, click the blue “Scan Now” button, and the results should let you know if there are any security or stability updates available for your installed plug-ins (a list of the plug-ins and add-ons that this program can check is available here). Clicking the blue “Fix It” button next to each action item listed fetches the appropriate installer from the vendor’s site and prompts you to download and install it. Re-scan as needed until the browser plug-ins are up to date.

Secunia has long had a very similar capability built into its free Personal Software Inspector program, but I realize not everyone wants to install a new program + Windows service to stay abreast of the latest patches (Secunia also offers a Web-based scan, but it requires Java, a plug-in that I have urged users to ditch if possible). The nice thing about Qualys’ plug-in approach is that it works not only on Windows, but also on Mac and Linux machines. On Windows 64-bit systems, only the 32-bit version of Internet Explorer is supported, and the plug-in thankfully nudges IE6 and IE7 users to upgrade to at least IE8.

Having the latest browser updates in one, easy-to-manage page is nice, but remember that the installers you download may by default come with additional programs bundled by the various plug-in makers. For example, when I updated Adobe’s Shockwave player on my test machine, the option to install  Registry Mechanic was pre-checked. The same thing happened when I went to update my Foxit Reader plug-in, which wanted to set Ask.com as my default search provider, set ask.com as my home page, and have the Foxit toolbar added.

Microsoft Issues Emergency Fix for IE Flaw

Microsoft has issued an emergency security update to plug a critical hole in its Internet Explorer Web browser. The IE bug is the same flaw that is being blamed in part for fueling a spate of recent break-ins at Fortune 100 companies, including Google and Adobe.

If you use Microsoft Windows, please take a moment now to update your computer. Updates are available for all supported versions of IE and Windows.  The easiest way to install the patch is through Windows Update.  Users who have Automatic Updates turned on may be prompted to download and apply this within the next 48 hours or so, but honestly this is the kind of bug you probably want to quash as soon as possible.

The reason is that this is a browse-to-a-hostile-site-and-quickly-have-a-bad-day kind of flaw. What’s more, Symantec is now reporting that it has discovered hundreds of malicious and/or hacked Web sites are now serving up code that exploits this flaw to download malicious software. While many of these sites are in China, that fact matters little because hackers can always stitch code into a hacked, legitimate site that quietly and invisibly pulls down exploits from other sites. Meanwhile, security firm Websense warns that the targeted e-mail attacks leveraging this flaw continue unabated.

When computer code that exploits this IE flaw was first posted online last week, Microsoft was quick to point out that it had only seen the code working reliably against IE6 users. However, researchers now claim that the exploit can also be made to work against IE7 and even IE8 — the latest version of IE that ships with Windows 7 systems.

The fixes included in this patch aren’t limited to the publicly disclosed flaw: Microsoft has addressed seven other vulnerabilities in this patch as well. More details about this specific update are available at this Microsoft Technet page.
