"The version of LibreOffice installed on the remote Mac OS X host is
prior to 5.0.5. It is, therefore, affected by multiple
vulnerabilities :

  - A remote code execution vulnerability exists due to
    improper validation of user-supplied input when handling
    LotusWordPro (LWP) documents. A remote attacker can
    exploit this, via a crafted LWP document, to corrupt
    memory, resulting in a denial of service condition or
    the execution of arbitrary code. (CVE-2016-0794)

  - A remote code execution vulnerability exists due to
    improper validation of user-supplied input when handling
    LwpTocSuperLayout records. A remote attacker can exploit
    this, via a crafted LwpTocSuperLayout record in a
    LotusWordPro (LWP) document, to corrupt memory,
    resulting in a denial of service condition or the
    execution of arbitrary code. (CVE-2016-0795)

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