A remote attacker could entice a user to open a specially crafted web page using Opera, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. Furthermore, a remote attacker may be able to trick a user into downloading and executing files, conduct Cross-Site Scripting (XSS) attacks, spoof the address bar, or have other unspecified impact.
There is no known workaround at this time.
