23 vulnerabilities squashed by Microsoft's Patch Tuesday effort



This month's Patch Tuesday saw Microsoft release eight bulletins addressing 23 vulnerabilities. If you run a still-supported version of Windows, there's a patch for you this month.

Actually, that's not quite true - if you are responsible only for Server Core installations of Windows Server 2008, then you might not have any patches to apply. But the critical patches for the .NET Framework 1, 2 and 4 (for issues exploitable in part via Silverlight), and Internet Explorer 6, 7, 8 and 9 mean most Windows users and administrators will have something to apply as a matter of urgency.


The remaining six bulletins are all rated important, even though four of the issues have the potential for remote code execution. Those updates concern Microsoft Active Accessibility, Windows Media Center, Forefront Unified Access Gateway, and Windows Kernel-Mode Drivers.

A patch for the Windows Ancillary Function Driver addresses a privilege escalation issue, while the bulletin for Host Integration Server fixes a pair of denial of service issues.

While Microsoft recommends that all the updates are installed as soon as possible, it understandably recommends that the two critical bulletins be prioritised as reliable exploits are expected within 30 days.

Unusually, all eight bulletins apply to Windows 7 while XP and Vista have six each.

Active Vs. Passive DWDM Solutions

An active approach to your growing optical transport network & connectivity needs.

Building dark fibre network infrastructure using WDM technology used to be considered a complex challenge that only carriers have the means to implement.

This has led many enterprises to build passive networks, which are inferior in quality and ultimately limit their future growth.

Why are passive solutions considered inferior? And what makes active solutions great?

Read more about these two solutions, and how PacketLight fits into all this.
