tag_summary = "The remote host is using Opera - an alternative web browser.

  This version reportedly occurs when processing a 'news:' URL
  of excessive length, that may result in a denial of service.
  It has been reported that this issue will trigger a condition
  that will prevent Opera from functioning until the program
  has been reinstalled.

  solution : Install Opera 7.20 or newer.";
