Microsoft Internet Explorer contains a race condition that results in a cross-domain violation.
Internet Explorer uses a cross-domain security model to maintain separation between browser frames from different sources. This model is designed to prevent code in one domain from accessing data in a different domain. The Internet Security Manager Object determines which zone or domain a URL exists in and what actions can be performed.
A race condition in Internet Explorer may allow an attacker to evade the cross-domain security model. Note that Internet Explorer 6 and Internet Explorer 7 are affected by this vulnerability.
A website in one domain has the ability to access information in another domain. The website may also be able to execute scripts or take other actions that are permitted in the other domain.
We are currently unaware of a practical solution to this problem.
