"The version of tested product installed on the remote host is prior to
tested version. It is, therefore, affected by a stack based overflow 
vulnerability in the Junos OS Packet Forwarding Engine manager (FXPC)
process on QFX5000 series. A remote attacker can exploit it which can
lead to a remote code execution  as referenced in the JSA10930 advisory.
Note that Nessus has not tested for this issue but has instead relied only
 on the application's self-reported version number.");
