Description

Image.Load throws IndexOutOfRangeException when loading malformed JPG file.

Steps to Reproduce

Run the following code snippet with the path variable containing the path to one of the files from the attached archive:

Image.Load(path);

There are eight different stack traces in total for this exception type, which is why I bundled them together in a single issue (also, I'm not sure which one of these might be the part of the same issue, because some stack traces look quite similar). Here are all the stack traces:
