"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.

  - It may be possible to make Wireshark crash by
    injecting a malformed packet onto the wire or by
    convincing someone to read a malformed packet trace
    file. (wireshark-bug-16476)

Note that Nessus has not tested for this issue but has instead
relied only on the application's self-reported version number.");
