MS12-009: Vulnerabilities in Ancillary Function Driver Could Allow Elevation of Privilege (2645640)

High Nessus Plugin ID 57943


The remote Windows host contains a driver that allows privilege escalation.


The remote Windows host contains a version of the Ancillary Function Driver (afd.sys), which has multiple flaws that prevent it from properly validating input before passing it from user mode to the kernel.

An attacker with local access to the affected system could exploit these issues to execute arbitrary code in kernel mode and take complete control of the affected system.


Microsoft has released a set of patches for Windows XP x64, 2003, Vista, 2008 SP2, 7, and 2008 R2.
