Description

While reviewing some code I realized that there is no bounds checking on ArrowBuf slicing. Example negative test case that should pass but is currently failing can be found here:

It may be that this doesn't cause more problems because the index checks do exist on memory access but fixing this would make it much easier to understand where a code mistake was made.
