Description:
A vulnerability has been reported in Microsoft Windows, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in an RPC interface of the DNS service used for remote management of the service. This can be exploited to cause a stack-based buffer overflow via a specially crafted RPC request.

Successful exploitation allows execution of arbitrary code with SYSTEM privileges.

NOTE: According to Microsoft, this is already being actively exploited on a limited scale.
