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:
