Language:

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 3.2.5. It is, therefore, affected by a vulnerability as referenced in the wireshark-3.2.5 advisory.

- The GVCP dissector could go into an infinite loop. It may be possible to make Wireshark consume excessive CPU resources by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. (CVE-2020-15466)

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 3.2.5 or later.
