"The version of Opera installed on the remote host is a version prior
to version 21. It is, therefore, reportedly affected by multiple
address bar spoofing vulnerabilities :

  - Several errors exist related to downloads, download
    pop-up dialogs, and the address bar that could allow
    URLs to be displayed incorrectly, leading to spoofing
    possibilities. (DNA-17861, DNA-18354)

  - An error exists related to address bar displays, data
    URIs and opening downloads in new tabs that could allow
    URLs to be displayed incorrectly, leading to spoofing
    possibilities. (DNA-19280)");
