Attack could overload Net
A method of exploiting the Transmission Control Protocol (TCP) could, in theory, clog large sections of the Internet, according to a report by University of Maryland researchers. The vulnerability, first uncovered six years ago, could be used to bring the world's information circulatory system to a virtual standstill, according to the report.

The CERT Coordination Center, which tracks computer and network security threats, has issued a vulnerability note about the security hole
