The remote device is missing a vendor-supplied security patch.


According to its self-reported version number, the remote Juniper Junos device is affected by a denial of service vulnerability due to a flaw in the Spanning Tree Protocol implementation. An unauthenticated, remote attacker can exploit this, via specially crafted packets that create an artificial loop in the network topology, to cause excessive bandwidth usage.
