Description: A vulnerability was reported in Windows in the Winsock and DNS client code. A remote user can execute arbitrary code on the target system.
A remote user can create specially crafted HTML that, when loaded by the target user, will trigger a buffer overflow in the Winsock
API and execute arbitrary code on the target system.
A remote user can also send specially crafted DNS data to trigger a buffer
overflow in the Windows DNS client layer and execute arbitrary code on the target system. The code will run with the privileges
of the target service.
Microsoft credits Peter Winter Smith of NGS Software with reporting the Winsock Hostname vulnerability
and Mark Dowd of ISS X-Force with reporting the DNS Client Buffer Overrun vulnerability.
