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

  - incomplete blacklist vulnerability in includes/upload/UploadBase.php allows remote attackers to inject arbitrary web
  script or HTML via an application/xml MIME type for a nested SVG with a data: URI.

  - incomplete blacklist vulnerability allows remote attackers to inject arbitrary web script or HTML via an animated href XLink element.

  - MediaWiki does not properly handle when the Zend interpreter xml_parse function does not expand entities, which allows remote attackers
  to inject arbitrary web script or HTML via a crafted SVG file.

  - bypassing the SVG filtering and obtain sensitive user information via a mixed case @import in a style element in an SVG file.

  - when using HHVM or Zend PHP, allows remote attackers to cause a denial of service ('quadratic blowup' and memory consumption) via an XML file containing an
  entity declaration with long replacement text and many references to this entity, a different vulnerability than CVE-2015-2942.

  - Cross-site scripting (XSS) vulnerability allowing remote attackers to inject arbitrary web script or HTML via a custom JavaScript file, which is not properly
  handled when previewing the file.

  - Cross-site scripting (XSS) vulnerability, when using HHVM, allows remote attackers to inject arbitrary web script or HTML via an invalid parameter in a wddx
  format request to api.php, which is not properly handled in an error message, related to unsafe calls to wddx_serialize_value.

  - when using HHVM, allows remote attackers to cause a denial of service (CPU and memory consumption) via a large number of nested entity references in an (1) SVG
  file or (2) XMP metadata in a PDF file, aka a 'billion laughs attack', a different vulnerability than CVE-2015-2937.");
