Fixes #9579 Protect against panics caused by integer overflows by using functions that allow integer overflows to be caught instead of causing a panic. Also protect against DOS from images that might not cause an overflow but do consume an absurd amount of memory by limiting images to a maximum size of 4GiB (which is the maximum size of `image-storage-limit`).
