Opera Multiple Vulnerabilities

Multiple vulnerabilities have been identified in Opera, which can be exploited by malicious people to conduct spoofing attacks and bypass certain security restrictions.

1. An error when displaying preferences within a small window can be exploited to e.g. execute arbitrary code by tricking a user into entering a specific keyboard sequence.
2. An error when displaying pop-up windows can be exploited to execute script code by tricking a user into following a specific sequence of events.
3. An error when handling JSON resources can be exploited to bypass the cross-domain policy restriction and disclose certain information to other sites.
4. An unspecified error can be exploited to display arbitrary content while showing the URL of a trusted web site in the address bar.
5. An error when handling page loads can be exploited to display arbitrary content while showing the URL of a trusted web site in the address bar.
