> DESCRIPTION:
> Secunia Research has discovered a weakness in Opera, which can be
> exploited to display the SSL certificate from a trusted site on an
> untrusted site.
> 
> The weakness is caused due to Opera not resetting the SSL security
> bar after displaying a download dialog from a SSL enabled web site.
> This allows an untrusted web site to display yellow SSL security bar
> from a trusted web site.
> 
> NOTE: A more convincing exploit can be done using pop-up windows,
> which do not have a visible address bar.
> 
> The weakness has been confirmed in Opera 8.54. Prior versions may
> also be affected.
> 
> SOLUTION:
> Upgrade to version 9.0.
