The version of Wireshark installed on the remote Windows host is prior to 3.2.9. It is, therefore, affected by multiple vulnerabilities as referenced in the wireshark-3.2.9 advisory.
Memory leak in Kafka protocol dissector in Wireshark 3.4.0 and 3.2.0 to 3.2.8 allows denial of service via packet injection or crafted capture file. (CVE-2020-26418)
Crash in USB HID protocol dissector and possibly other dissectors in Wireshark 3.4.0 and 3.2.0 to 3.2.8 allows denial of service via packet injection or crafted capture file. (CVE-2020-26421)
Memory leak in RTPS protocol dissector in Wireshark 3.4.0 and 3.2.0 to 3.2.8 allows denial of service via packet injection or crafted capture file. (CVE-2020-26420)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
