> 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.
> 
> SOLUTION:
> The vendor recommends disabling the remote management over RPC
> capability for DNS servers.
> 
> PROVIDED AND/OR DISCOVERED BY:
