Name of the Vulnerable Software and Affected Versions Windows Vista versions SP1 through SP2 Windows Server 2008 versions Gold through R2 SP1 Windows 7 versions Gold through SP1

Description The issue allows local users to gain privileges via a crafted application that triggers a NULL pointer dereference. An elevation of privilege vulnerability exists due to the way that Windows kernel-mode drivers manage pointers to kernel-mode driver objects. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode, enabling them to install programs, view, change, or delete data, or create new accounts with full administrative rights.

Recommendations For Windows Vista versions SP1 through SP2, update to a newer version to mitigate the risk. For Windows Server 2008 versions Gold through R2 SP1, update to a newer version to mitigate the risk. For Windows 7 versions Gold through SP1, update to a newer version to mitigate the risk.
