Patch Tuesday is upon us again, this time addressing eight security vulnerabilities. One update will patch the Internet Explorer issue that has been exploited recently.

Security experts identified the IE update as the one to deploy first, citing the fact that one of the vulnerabilities has been used by cyber criminals in targeted attacks against users in Japan and Taiwan.

On Sept. 17, Microsoft confirmed that hackers were exploiting a critical unpatched vulnerability in Internet Explorer 8 (IE8) and Internet Explorer 9 (IE9). The bug, however, existed in all versions of the browser, including the 12-year-old IE6 and the newest IE11.

The IE update was just one of four rated "critical" by Microsoft. The remaining three critical updates were all aimed at Windows, including one that applied to the newest Windows 8, Windows RT, Windows 8.1 and Windows RT 8.1, according to Microsoft's advanced notification distributed today.

Experts recommended that customers install the Windows updates as soon as possible after their release. "Bulletins 2 and 3 are through the stack and might end up rating more attention than the IE update," warned Storms.
