Description:
Secunia Research has discovered a vulnerability in Opera, which can be exploited by malicious web sites to spoof dialog boxes.
The problem is that JavaScript dialog boxes do not display or include their origin, which allows a new window to open e.g. a prompt dialog box, which appears to be from a trusted site.
Successful exploitation normally requires that a user is tricked into opening a link from a malicious web site to a trusted web site.
Secunia has constructed a test, which can be used to check if your browser is affected by this issue:

The vulnerability has been confirmed in version 8.0. 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:
Update to version 8.01.
