The version of Wireshark installed on the remote Windows host is prior to 2.6.17. It is, therefore, affected by a DoS vulnerability as referenced in the wireshark-2.6.17 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
