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.
