Microsoft Windows 95 and 98 with multiple TCP/IP stacks ICMP packet denial of service
|win-multiple-ip-dos (7542)||Medium Risk|
Microsoft Windows 95 and 98 clients with multiple TCP/IP stacks bound to the same MAC address are vulnerable to a denial of service attack. If a remote attacker pings an affected host, the host responds with one ACK packet for each TCP/IP stack loaded on the host. This could create collisions on the subnet, which would disrupt network functionality.

- CVE-1999-1201: Windows 95 and Windows 98 systems, when configured with multiple TCP/IP stacks bound to the same MAC address, allow remote attackers to cause a denial of service (traffic amplification) via a certain ICMP echo (ping) packet, which causes all stacks to send a ping response, aka TCP Chorusing.
