Microsoft Windows Ancillary Function Driver privilege escalation
|ms-ancillary-function-priv-esc (72840)||High Risk|
The Microsoft Windows Ancillary Function Driver (afd.sys) could allow a local attacker to gain elevated privileges on the system, caused by improper validation of input passed from user mode to the kernel. By executing a malicious application on the vulnerable system, a local attacker with valid login credentials could exploit this vulnerability to execute arbitrary code on the system with elevated privileges.
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS12-009. See References.
