Description of the vulnerability
When a computer provides Internet Connection Sharing (ICS), it is connected to internet, and computers on the internal network use it as a proxy.
However, the ICS service of Windows does not correctly manage DNS queries with no Resource Record. This error occurs in ipnathlp.dll and stops svchost.exe.
An attacker on the internal network can therefore generate a denial of service.
