Vulnerability Name:

CCN-1771

Published:1999-02-06
Updated:1999-02-06
Summary:Both Windows 95 and 98 have the ability to have multiple TCP/IP stacks bound to a single Ethernet NIC. When such a situation exists, each stack responds to client IPs with multiple responses occurring at slightly different instances (the time difference is where the name "chorusing" is derived). If a network has a multiple system setup in such a manner it is easy to cause the network to become overloaded and deny legitimate bandwidth.
