"The version of Opera installed on the remote host is earlier than
12.01 and is, therefore, reportedly affected by multiple issues :

  - An error exists in the handling of certain URLs that
    can lead to memory corruption and possible code
    execution. (1016)

  - Errors exist in the handling of DOM elements and
    certain HTML characters that can lead to cross-site
    scripting. (1025, 1026)

  - Download dialog boxes can be made small enough that
    users may not realize they are accepting a download
    and further, executing such a download. (1027)

  - An attacker could cause an application crash by tricking
    a user into connecting to a malicious site, as 
    demonstrated by the Lenovo 'Shop Now' page.
