In Wireshark through 3.2.7, the Facebook Zero Protocol (aka FBZERO) dissector could enter an infinite loop. This was addressed in epan/dissectors/packet-fbzero.c by correcting the implementation of offset advancement.

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.
