Hi, Firefox 2.0.0.18 <http://2.0.0.18> fixes a cross-domain theft of image data. Firefox 3 unaffected. It's another interesting case where a redirector confuses the browser about the true origin of a piece of content. If evil.org <http://evil.org> hosts a redirector, e.g. evil.org/redir <http://evil.org/redir>, and an image is loaded via this redirector, the image will be treated as a same-domain image. In this event, the image pixel data may easily be stolen by rendering the image to a canvas and using the getImageData() JavaScript API.
