"The Network Location Awareness (NLA) service on the remote host is
affected by a security bypass vulnerability due to a failure to
validate whether it is connected to a trusted domain or an untrusted
network. This could cause the system to unintentionally configure
applications insecurely (e.g. the firewall policy) when connecting to
an untrusted network. An attacker on the same network can exploit this
by spoofing responses to DNS or LDAP requests made by the targeted
system.

Note that Microsoft has no plans to release an update for Windows 2003
even though it is affected by this vulnerability.");
