Description

What does this rule detect?

It is possible to concatenation a zip on the end of a jpeg. It will still open and parse as a jpeg and it will also be able to be unzipped. This seems like an unusual thing that might be worth reporting on.

Does this require the addition of a new operation to the parser?
