Medium Nessus Plugin ID 66514
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionAccording to its self-reported version number, the remote Junos device has a denial of service vulnerability. Receiving Ethernet packets with an invalid Ether-type can cause congestion on routers with line cards installed using Ichip-based FPCs and DPCs. An unauthenticated attacker on the same subnet could exploit this, causing the router to drop valid protocol traffic.
