Vulnerability Information

USB Mass Storage Elevation of Privilege Vulnerability-CVE-2016-0133

This security update resolves an elevation of privilege vulnerability in 
Microsoft Windows when the Windows USB Mass Storage Class driver fails to 
properly validate objects in memory. An attacker who successfully exploited 
this vulnerability could run arbitrary code in kernel mode. An attacker could
then install programs; view, change, or delete data; or create new accounts 
with full user rights.

To exploit this vulnerability, an attacker would first have to have physical 
access to the system. An attacker could then insert a specially crafted USB 
device that could exploit the vulnerability and take control of an affected 
system. The update addresses this vulnerability by correcting how the Windows
USB Mass Storage Class driver handles objects in memory.

The following table contains a link to the standard entry for each 
vulnerability in the Common Vulnerabilities and Exposures list:

Vulnerability Title 					CVE number 	Publicly disclosed 	Exploited

USB Mass Storage Elevation of Privilege Vulnerability 	CVE-2016-0133	No 			No
