Loading this BMP and then refreshing a few times will trigger 100% CPU usage and the only way to stop it seems to be to close the browser.

This looks like a dup of bug 1241728. It is spending a loooong time (though it will complete eventually) trying to resize/convolve a 3616 x 637534240 image. But the filter chosen in this case doesn't trigger the OOM. However, even without the OOM, it's still spinning. So perhaps your proposed decoder size limits will take care of this one too?

Yes, the size limits should fix this. tnikkel has a patch limiting each dimensions to 1<<20.
