"The version of LibreOffice installed on the remote Windows host is
either 5.x prior to 5.4.5 or 6.x prior to 6.0.1. It is, therefore,
affected by the following vulnerabilities:

  - An arbitrary file read vulnerability exists in the
    COM.MICROSOFT.WEBSERVICE function due to improper
    validation of a URL input. An unauthenticated, remote
    attacker can exploit this, via a specially crafted file,
    to read arbitrary files and disclose sensitive information.
    (CVE-2018-6871)

  - A use after free vulnerability exists in the StgSmallStrm
    class due to the use of a short data type. An unauthenticated,
    remote attacker can exploit this, via a specially crafted
    file that uses the structured storage ole2 wrapper, to
    execute arbitrary code. (CVE-2018-10119)

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