(Opera: Multiple spoofing vulnerabilities)

    Opera fails to remove illegal characters from an URI of a link and to check
    that the target frame of a link belongs to the same website as the link.
    Opera also updates the address bar before loading a page. Additionally,
    Opera contains a certificate verification problem.
  
Impact :

    These vulnerabilities could allow an attacker to impersonate legitimate
    websites to steal sensitive information from users. This could be done by
    obfuscating the real URI of a link or by injecting a malicious frame into
    an arbitrary frame of another browser window.
  
Workaround :

    There is no known workaround at this time. All users are encouraged to
    upgrade to the latest available version.");
