In Wireshark 3.2.0 to 3.2.2, 3.0.0 to 3.0.9, and 2.6.0 to 2.6.15, the BACapp dissector could crash. This was addressed in epan/dissectors/packet-bacapp.c by limiting the amount of recursion.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - In Wireshark 2.4.0 to 2.4.3 and 2.2.0 to 2.2.11, the IxVeriWave file parser could crash. This was     addressed in wiretap/vwr.c by correcting the signature timestamp bounds checks. (CVE-2018-5334)

  - In Wireshark 2.4.0 to 2.4.3 and 2.2.0 to 2.2.11, the WCP dissector could crash. This was addressed in     epan/dissectors/packet-wcp.c by validating the available buffer length. (CVE-2018-5335)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote host is affected by the vulnerability described in GLSA-202007-13 (Wireshark: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Wireshark. Please       review the CVE identifiers referenced below for details.
  Impact :

    Please review the referenced CVE identifiers for details.
  Workaround :

    There is no known workaround at this time.

The version of Wireshark installed on the remote Windows host is 2.6.x prior to 2.6.16, 3.0.x prior to 3.0.10, or 3.2.x prior to 3.2.3.
It is, therefore, affected by a vulnerability in the BACapp dissector where injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file can crash Wireshark.

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 2.6.x prior to 2.6.16, 3.0.x prior to 3.0.10, or 3.2.x prior to 3.2.3.
It is, therefore, affected by a vulnerability in the BACapp dissector where injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file can crash Wireshark.

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