Flash Player vulnerable in handling cross-domain policy files

Adobe Flash Player contains a vulnerability caused by improper handling of cross-domain policy files.

Adobe Flash Player is a player for the Flash media format and enables frame-based animations with sound to be viewed within a web browser.
According to Adobe's "About allowing cross-domain data loading", "When a Flash document attempts to access data from another domain, Flash Player automatically attempts to load a policy file from that domain. If the domain of the Flash document that is attempting to access the data is included in the policy file, the data is automatically accessible."
Flash Player contains a vulnerability that may allow a specially crafted web page to be interpreted as a cross-domain policy file because the plugin fails to properly handle cross-domain policy files.
