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.

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