Exploited by Malware: True

Synopsis

An application installed on the remote host is affected by an an arbitrary code execution vulnerability.

Description

The version of LibreOffice installed on the remote macOS host is 6.1.x prior to 6.1.3.2. It is, therefore, affected by an an arbitrary code execution vulnerability as a result of a path traversal vulnerability allowing the ability to run any local python script, in addition to being able to pass user defined parameters to default python modules and functions included with libreoffice.

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

Solution

Upgrade to LibreOffice version 6.1.3.2 or later.
