Buffer overflow in the CreateDIBPalette function in win32k.sys in Microsoft Windows XP SP3, Server 2003 R2 Enterprise SP2, Vista Business SP1, Windows 7, and Server 2008 SP2 allows local users to cause a denial of service (crash) and possibly execute arbitrary code by performing a clipboard operation (GetClipboardData API function) with a crafted bitmap with a palette that contains a large number of colors.

The kernel-mode drivers in Microsoft Windows XP SP3 do not properly perform indexing of a function-pointer table during the loading of keyboard layouts from disk, which allows local users to gain privileges via a crafted application, as demonstrated in the wild in July 2010 by the Stuxnet worm, aka "Win32k Keyboard Layout Vulnerability."
