  - Specially crafted domain names can cause a memory

    possibly remote code execution. (938)

  - Opera may allow scripts to run on the feed subscription
    page, thereby gaining access to the feeds object. (939)

  - In some cases, a Web font intended to be used for page 
    content could be incorrectly used by Opera to render 
    parts of the user interface, including the address 
    field. (940)"  );
