  - The Trusts root X.509 certificates signed with the MD2 algorithm, which
    makes it easier for man-in-the-middle attackers to spoof arbitrary SSL
    servers via a crafted server certificate.
  - Opera fails to check all intermediate X.509 certificates for revocation.
  - When a collapsed address bar is used, Opera does not properly update the
    domain name from the previously visited site to the currently visited site.

    (IDN) in the address bar.";
