"The version of Wireshark installed on the remote Windows host is prior to 3.2.5. It is, therefore, affected by a
vulnerability as referenced in the wireshark-3.2.5 advisory.

  - The GVCP dissector could go into an infinite loop. It
    may be possible to make Wireshark consume excessive CPU
    resources by injecting a malformed packet onto the wire
    or by convincing someone to read a malformed packet
    trace file. (CVE-2020-15466)

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