"The version of Wireshark installed on the remote Windows host is prior to 3.4.2. It is, therefore, affected by a
vulnerability as referenced in the wireshark-3.4.2 advisory.

  - The QUIC dissector could crash. 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. (CVE-2020-26422)

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