Microsoft Patches 19 Security Holes

Summary: Microsoft released six software updates fixing at least 19 security holes in Windows and other products, 13 of them rated critical, meaning they could be exploited without user help. The batch includes a critical Internet Explorer 9 update fixing three flaws, plus critical fixes for the Windows shell and Windows Kernel present in nearly all supported Windows versions, and updates for .NET Framework, Excel, and IIS.

Why it matters: All of the critical updates earned the most dire marks on Microsoft's exploitability index, which estimates the likelihood attackers will build remote code execution and denial of service exploits within 30 days of release - so the window to patch is measured in days, not months.
