"The version of Opera installed on the remote host is earlier than
10.61.  Such versions are potentially affected by the following 
issues :

  - A heap overflow when performing painting operations on
    an HTML5 canvas can result in execution of arbitrary
    code. (966)

  - An issue with tab focus is open to an attack
    where it is used to obscure a download dialog that is in
    another tab. The user can be tricked into clicking on
    buttons in the dialog, resulting in the downloaded file 
    being executed. (967)

  - Certain types of content concerning the news feed
    preview do not have their scripts removed properly,
    possibly resulting in subscription of feeds without
    the user's consent. (968)

  - Loading an animated PNG image may cause high CPU usage 
    with no response from the browser. (CVE-2010-3021)

  - An error exists in the handling of 'SELECT' HTML 
    elements having a very large 'size' attribute. This
    error can allow memory corruption and possibly allows
    remote code execution. (CVE-2011-1824)"
