Description

The Fibre Channel over Ethernet (FCoE) feature in IBM System Networking and Blade Network Technology (BNT) switches running IBM Networking Operating System (aka NOS, formerly BLADE Operating System) floods data frames with unknown MAC addresses out on all interfaces on the same VLAN, which might allow remote attackers to obtain sensitive information in opportunistic circumstances by eavesdropping on the broadcast domain. IBM X-Force ID: 83166.
