OMG, it's that time of the month again. The time for System Admins to earn their pay. big grin Microsoft will be rolling out 12 updates addressing 57 vulnerabilities across the range of Microsoft platforms, five of which are classified as critical. The bugs stretch across a range of programs, including Windows, Internet Explorer, Windows Server, Microsoft Exchange, and Microsoft's .Net Framework. Five of the 12 patches are rated critical, so they're designed to patch holes that could allow someone to execute malicious code on an unprotected PC. Two of the critical patches are aimed at all versions of Internet Explorer from 6 through 10. That means all current versions of Windows with IE installed are at risk, including Windows 8 and Windows RT. The third critical patch is geared toward Windows XP and Vista as well as Server 2003, while the fourth applies only to Microsoft Exchange. The fifth critical one affects just Windows XP.
