"The version of Apache OpenOffice installed on the remote host is a
version prior to 4.1.3. It is, therefore, affected by the following
vulnerabilities :

  - A memory corruption issue exists in the Impress tool due
    to improper validation of user-supplied input when
    handling elements in invalid presentations. An
    unauthenticated, remote attacker can exploit this, via
    specially crafted MetaActions in an ODP or OTP file, to
    cause a denial of service condition or the execution of
    arbitrary code. (CVE-2016-1513)

  - A privilege escalation vulnerability exists due to the
    use of an unquoted Windows search path. A local attacker
    can exploit this to execute arbitrary code with elevated
    privileges. (CVE-2016-6803)

  - A privilege escalation vulnerability exists due to the
    use of a fixed path to load system binaries. A local
    attacker can exploit this, via a specially crafted DLL
    file in the library path, to inject and execute
    arbitrary code with elevated privileges. (CVE-2016-6804)");
