Vulnerability Information

Multiple Windows Mount Point Elevation of Privilege Vulnerabilities

Multiple vulnerabilities exist in Windows while validating reparse
points being set by sandbox applications. An attacker who successfully
exploited the vulnerabilities could run arbitrary code in the security
context of the local system. An attacker could then install programs;
view, change, or delete data; or create new accounts with full user
rights.

To exploit the vulnerabilities, an attacker would first have to log on
to the system. An attacker could then run a specially crafted
application that could exploit the vulnerabilities and take complete
control of an affected system. The update addresses the vulnerabilities
by correcting how Windows handles certain scenarios involving mount
point creation.
