"The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-6262-1 advisory.

  - In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This was
    addressed in epan/dissectors/packet-nfs.c by preventing excessive recursion, such as for a cycle in the
    directory graph on a filesystem. (CVE-2020-13164)

  - In Wireshark 3.2.0 to 3.2.4, the GVCP dissector could go into an infinite loop. This was addressed in
    epan/dissectors/packet-gvcp.c by ensuring that an offset increases in all situations. (CVE-2020-15466)

  - In Wireshark 3.2.0 to 3.2.5, the Kafka protocol dissector could crash. This was addressed in
    epan/dissectors/packet-kafka.c by avoiding a double free during LZ4 decompression. (CVE-2020-17498)

  - In Wireshark 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and 2.6.0 to 2.6.20, the TCP dissector could crash. This was
    addressed in epan/dissectors/packet-tcp.c by changing the handling of the invalid 0xFFFF checksum.
    (CVE-2020-25862)

  - In Wireshark 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and 2.6.0 to 2.6.20, the MIME Multipart dissector could
    crash. This was addressed in epan/dissectors/packet-multipart.c by correcting the deallocation of invalid
    MIME parts. (CVE-2020-25863)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
