tag_summary = "The remote host is using Opera - an alternative web browser.
  This version contains a flaw that may allow a malicious user
  to trick a user into running arbitrary code.
  The issue is triggered when an malicious web site provides a file for download,
  but crafts the filename in such a way that the file is executed, rather than saved.
  It is possible that the flaw may allow arbitrary code execution resulting in a
  loss of confidentiality, integrity, and/or availability.

  Solution : Install Opera 7.50 or newer.";
