Vulnerability Information

Group Policy Remote Code Execution Vulnerability - CVE-2015-0008

A remote code execution vulnerability exists in how Group Policy receives and
applies policy data when a domain-joined system connects to a domain 
controller. To exploit this vulnerability, an attacker would have to convince
a victim with a domain-configured system to connect to an attacker-controlled
network.

An attacker who successfully exploited this vulnerability could take complete
control of an affected system and then install programs; view, change, or 
delete data; or create new accounts with full user rights. The security update
addresses the vulnerability by improving how domain-configured systems connect
to domain controllers prior to Group Policy accepting configuration data.

This vulnerability has not been publicly disclosed. When this security 
bulletin was issued, Microsoft had not received any information to indicate 
that this vulnerability had been publicly used to attack customers.
