    Multiple vulnerabilities have been discovered in Opera. Please review
      the CVE identifiers 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 obtain sensitive
      information, conduct Cross-Site Scripting (XSS) attacks, or bypass
      security restrictions.
    A local attacker may be able to obtain sensitive information.
  
Workaround :

    There is no known workaround at this time."
