Critical Windows bugs to be patched next week


Microsoft today announced it would release just two security updates next week to patch three vulnerabilities in Windows.

One of the two was tagged with the “critical” label, Microsoft’s highest threat ranking, while the other was marked “important.” Microsoft typically assigns a critical rating to vulnerabilities that can be exploited with little or no action on the part of a user.

Both updates will patch flaws in Windows.

What Microsoft pegged as “Bulletin 1” in the advance notification it published today will affect only Windows Vista, while “Bulletin 2” will affect all still-supported versions of the OS, with the client editions — XP, Vista and Windows 7 — labeled critical and the server software rated important.

“The Vista one is confusing,” said Andrew Storms, director of security operations at nCircle Security. “It’s either something introduced in Vista but doesn’t exist in Windows 7, or the component was rewritten for Windows 7.”

Storms speculated that the flaw might be in a part of operating system that’s little used, such as the task scheduler.

As for Bulletin 2, Microsoft’s bare bones write-up — typical of its advance warnings prior to Patch Tuesday — also doesn’t offer many clues.

“It’s critical in all the desktop clients and important in the server, and consistent in the whole stack,” said Storms, talking about Microsoft’s threat ratings. “The difference in the criticality is confusing, and Microsoft’s not giving us much to go on.”

The bug(s) patched by Bulletin 2 are most likely in an operating system DLL (dynamic-link library), said Storms, perhaps a driver or database connector, that’s crucial to the OS. (Source: ComputerWorld)

In my free time I enjoy spending time with my family, cooking and sports. My Christian faith is also important to me as a Missouri-Synod Lutheran and all my children attend a Lutheran grade school. When it comes to political leanings I am a conservative first and foremost which you will discover rather quickly. As for sports I am a huge fan of the Green Bay Packers.
