"The version of Wireshark installed on the remote macOS / Mac OS X host is prior to 2.6.11. It is, therefore, affected by
a vulnerability as referenced in the wireshark-2.6.11 advisory.

  - In Wireshark 3.0.0 to 3.0.3 and 2.6.0 to 2.6.10, the Gryphon dissector could go into an infinite loop.
    This was addressed in plugins/epan/gryphon/packet-gryphon.c by checking for a message length of zero.
    (CVE-2019-16319)

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