Microsoft Reissues Windows 2000 Server Security Fix

Microsoft today released an updated critical fix for Windows Media Services on Windows 2000 Server.

The revamped bulletin, MS10-025, addresses a "privately disclosed" bug that could enable remote code execution attacks. The bulletin was reissued less than a week after Microsoft pulled the initial fix from its April monthly security patch rollout.

Microsoft explained at that time that the fix did not "address the underlying issue effectively." The company added that it was not aware of active attacks seeking to exploit the vulnerability.

Some security experts believe that Microsoft recently received private, third-party reports that the patch didn't correctly address the vulnerability and therefore pulled it for a reconfiguration last week.

"For the most part, Microsoft's actions are likely to end up being viewed positively, but, at the same time, we can't help but wonder if they would take the same actions if the affected system were something more critical," said Andrew Storms, director of security at nCircle. "What if the patch involved IE or IIS or a newer OS like Windows7? In that case, it seems likely that Microsoft wouldn't have been so forthcoming, and they probably would have pushed the patch out faster in order to protect customers."

For its part, Microsoft says that the new update remedies the remote code execution exploit, which takes advantage of stack overflow in Windows Media Services. Windows Media Services is an option in Windows Server 2000 that supports streaming media applications.

Microsoft's security bulletin released today states that those who installed the earlier fix do not need to remove it before applying this update. In addition, the earlier fix will be updated by those who have turned on the automatic update feature in Windows. If automatic update is not enabled, the fix needs to be installed manually.
