According to Microsoft's advance notice for the August batch of patches, eight of the bulletins carry a "critical" severity rating. The other six are rated "important."
A critical bulletin typically covers vulnerabilities that could be exploited to launch remote code execution or drive-by-download attacks.
All versions of Windows are affected by the patches this month -- from Windows XP SP3 through Windows 7 and Windows Server 2008 R2.
The patches will ship on August 10, 2010.
