  Description :
  The remote host is using Opera, an alternative web browser.
  This version of Opera on the remote host fails to block write access to
  the 'location' object.  This could allow a user to create a specially
  crafted URL to overwrite methods within the 'location' object that would
  execute arbitrary code in a user's browser within the trust relationship
  between the browser and the server, leading to a loss of confidentiality
  and integrity.");
