SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionAccording to its self-reported version, the remote Juniper Junos OS device is affected by a denial of service (DoS) vulnerability. When a device running Juniper Networks Junos OS with MPC7, MPC8, or MPC9 line cards installed and the system is configured for inline IP reassembly, used by L2TP, MAP-E, GRE, and IPIP, the packet forwarding engine (PFE) will become disabled upon receipt of large packets requiring fragmentation. By continuously sending fragmented packets that cannot be reassembled, an unauthenticated, remote attacker can repeatedly disable the PFE causing a DoS.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
