"The remote host is affected by the vulnerability described in GLSA-202212-04 (LibreOffice: Arbitrary Code Execution)

  - LibreOffice supports Office URI Schemes to enable browser integration of LibreOffice with MS SharePoint
    server. An additional scheme 'vnd.libreoffice.command' specific to LibreOffice was added. In the affected
    versions of LibreOffice links using that scheme could be constructed to call internal macros with
    arbitrary arguments. Which when clicked on, or activated by document events, could result in arbitrary
    script execution without warning. This issue affects: The Document Foundation LibreOffice 7.4 versions
    prior to 7.4.1; 7.3 versions prior to 7.3.6. (CVE-2022-3140)

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