Name of the Vulnerable Software and Affected Versions Windows XP versions SP2 through SP3 Windows Server 2003 version SP2 Windows Vista versions SP1 through SP2 Windows Server 2008 versions Gold through SP2 and R2 Windows 7 (affected versions not specified)

Description The issue arises from improper validation of user-mode input by the win32k.sys driver in the kernel-mode drivers. This allows local users to gain privileges via a crafted application. An elevation of privilege vulnerability exists in the way that Windows kernel-mode drivers validate data supplied from user mode to kernel mode. An attacker who successfully exploits this could run arbitrary code in kernel mode and take complete control of an affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full administrative rights.

Recommendations For Windows XP versions SP2 through SP3, update to a newer version that includes the fix for this issue. For Windows Server 2003 version SP2, update to a newer version that includes the fix for this issue. For Windows Vista versions SP1 through SP2, update to a newer version that includes the fix for this issue. For Windows Server 2008 versions Gold through SP2 and R2, update to a newer version that includes the fix for this issue. For Windows 7, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
