event listener)
onSecurityError = function(fileRef:FileReference, errorString:String) {}

may have tried to access a SWF file outside its domain and does not have permission to do so.
You can try to remedy this error by using a cross-domain policy file.

Parameters
fileRef:FileReference - The FileReference object that initiated the operation.
errorString:String - Describes the error that caused onSecurityError to be called. The
value is "securitySandboxError".

including onSecurityError. The onSecurityError listener is triggered only if the upload
fails because of a security error.
