"The version of Opera installed on the remote host is earlier than 12.13
and is, therefore, reportedly affected by the following 
vulnerabilities :

  - An error exists related to DOM manipulation that could
    lead to application crashes or arbitrary code
    execution. (1042)

  - A use-after-free error exists related to SVG 'clipPaths'
    that could lead to memory corruption or arbitrary code
    execution. (1043)

  - An error exists related to the TLS protocol, CBC mode
    encryption and response time. An attacker could obtain
    plaintext contents of encrypted traffic via timing
    attacks. (1044)

  - The application could fail to make the proper 'pre-
    flight' Cross-Origin Resource Sharing (CORS) requests.
    In some situations this error could aid an attacker in
    cross-site request forgery (CSRF) attacks. (1045)

  - An unspecified, low severity issue exists that has an
    unspecified impact.");
