Stored XSS and content spoofing vulnerability in SWFUpload.
The utilities swfupload and video_player have been removed.
This affects anyone who is using the swfupload AlloyUI module or any of the associated swfupload_f*.swf and mpw_player.swf flash movies.
How should I update my code?
There are better, more standard ways to achieve upload currently. For instance, you can use A.Uploader to manage your uploads consistently across browsers.
For audio/video reproduction, you should update your code to use A.Audio and A.Video.
This change removes outdated code no longer being used in the platform. In addition, this change avoids future security issues from outdated flash movies.
