A remote attacker could entice a user to view a specially crafted web page, possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition. Furthermore, a remote attacker may be able to perform Man-in-the-Middle attacks, obtain sensitive information, spoof the address bar, conduct clickjacking attacks, bypass security restrictions and protection mechanisms, or have other unspecified impact.


There is no known workaround at this time.
