  script_tag(name:"vuldetect", value:"Checks if a vulnerable version is present on the target host.");

  script_tag(name:"insight", value:"Multiple flaws are due to:

  - Mac OS X Metafiles (WMF) can contain polygons which under certain circumstances
    when processed (split) can result in output polygons which have too many points
    to be represented by LibreOffice's internal polygon class.

  - Enhanced Metafiles (EMF) can contain bitmap data preceded by a header and a
    field with in that header which states the offset from the start of the header
    to the bitmap data. An emf can be crafted to provide an illegal offset.");

  script_tag(name:"impact", value:"Successful exploitation will allow
  attacker to execute arbitrary code within the context of the affected
  application. Failed exploit attempts will result in a denial-of-service
  condition.");
