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.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, using the Network Software Inspector.
Solution:
Upgrade to version 9.0.
