Name of the Vulnerable Software and Affected Versions
Windows XP versions SP2 and SP3
Windows Server 2003 version SP2
Windows Vista version SP2
Windows Server 2008 versions SP2, R2, and R2 SP1
Windows 7 versions Gold and SP1
Description
The issue arises from improper validation of user-mode input by the win32k.sys kernel-mode driver in Windows, allowing local users to potentially gain privileges or cause a denial of service through a crafted application. This could lead to a NULL pointer dereference and system crash. An attacker could exploit this to run arbitrary code in kernel mode, gaining complete control of the affected system, and then install programs, view, change, or delete data, or create new accounts with full administrative rights.
Recommendations
For Windows XP versions SP2 and SP3, update to a newer version to mitigate the risk.
For Windows Server 2003 version SP2, update to a newer version to mitigate the risk.
For Windows Vista version SP2, update to a newer version to mitigate the risk.
For Windows Server 2008 versions SP2, R2, and R2 SP1, update to a newer version to mitigate the risk.
For Windows 7 versions Gold and SP1, update to a newer version to mitigate the risk.
