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.

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 number.

The remote host is affected by the vulnerability described in GLSA-202008-14 (Wireshark: Denial of service)

    A double free error was discovered in Wireshark&rsquo;s Kafka dissector.
  Impact :

    A remote attacker could exploit these vulnerabilities by sending a       malformed packet or enticing a user to read a malformed packet trace       file, causing a Denial of Service.
  Workaround :

    There is no known workaround at this time.

The version of Wireshark installed on the remote Windows host is prior to 3.2.6. It is, therefore, affected by a vulnerability as referenced in the wireshark-3.2.6 advisory.

  - The Kafka 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-2020-17498)

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

The version of Wireshark installed on the remote macOS / Mac OS X host is prior to 3.2.6. It is, therefore, affected by a vulnerability as referenced in the wireshark-3.2.6 advisory.

  - The Kafka 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-2020-17498)
