Description:
h07 has discovered a vulnerability in Microsoft Windows, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to a NULL pointer dereference error in Windows NAT Helper Components (ipnathlp.dll). This can be exploited to crash the service via a specially crafted DNS query.
Successful exploitation requires that Internet Connection Sharing is enabled and the query is received from a client on the shared network interface.
The vulnerability is confirmed in a fully patched Windows XP SP2 system. Other versions may also be affected.
