Microsoft Black Tuesday: Big IE Update Trumps Windows & Office Patches

If you manage Windows networks, you know what time it is... time for Microsoft's monthly list of security updates.
Microsoft Patch day has gone live, and you can find a listing of today's security bulletins in their June Patch Day summary page. As expected, they released five security bulletins, one for Internet Explorer (IE), three for Windows and its components, and one for Office. They only rate the IE bulletin as Critical.
I recommend you focus most your attention to the IE update. It corrects 19 vulnerabilities—the bulk of today's flaw—and most of them could allow remote attackers to gain control of your users' computers via drive-by download attacks. You should definitely patch it first. That said, the Windows and Office updates are still important. Even though the Windows flaws require local access, and the Office flaw requires a bit of user interaction, they still pose some risk. So patch them too, just start with IE.
We'll share more details about Microsoft's bulletins in three upcoming alerts, posted throughout the day. Stay tuned. — Corey Nachreiner, CISSP (@SecAdept)MS Patch Day June 2013
