"The version of the tested product installed on the remote host is 
prior to the fixed version in the advisory. It is, therefore, affected
by a denial of service vulnerability that exists in RPD daemon. An 
unauthenticated, remote attacker can exploit this issue, by continuously
sending a specific Draft-Rosen MVPN control packet, to repeatedly crash
the RPD process causing a prolonged denial of service as referenced in
the JSA10879 advisory. 
Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
