Description

An elevation of privilege vulnerability exists in Windows when the Desktop Bridge VFS does not take into acccount user/kernel mode when managing file paths. 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 log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. The update addresses this vulnerability by correcting how the Windows Desktop Bridge VFS handles file path management.
