New! Plugin Severity Now Using CVSS v3

Synopsis

An application installed on the remote macOS / Mac OS X host is affected by a vulnerability.

Description

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)

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

Solution

Upgrade to Wireshark version 3.2.6 or later.
