  - Opera executes a mail application in situations where an 'IMG' element has
   a 'SRC' attribute that is a redirect to a mailto: URL, which allows remote
   attackers to launch excessive application via an HTML document with many
   images.

  - Improper handling of 'IFRAME' element with a mailto: URL in its 'SRC'
   attribute, which allows remote attackers to consume resources via an HTML
   document with many IFRAME elements.");
