    Multiple vulnerabilities have been discovered in Opera. Please review
      the CVE identifiers and Opera Release Notes referenced below for details.
  
Impact :

    A remote attacker could entice a user to open a specially crafted web
      page using Opera, possibly resulting in execution of arbitrary code with
      the privileges of the process or a Denial of Service condition.
      Furthermore, a remote attacker may be able to trick a user into
      downloading and executing files, conduct Cross-Site Scripting (XSS)
      attacks, spoof the address bar, or have other unspecified impact.
  
Workaround :

    There is no known workaround at this time."
