Description

When a malformed Arrow file containing an extremely large footer size (much larger than the file size) is fed to the ArrowFileReader, our implementation fails detect the problem, due to integer arithmetic overflow.

This will lead to extremely large memory allocation and eventually causing an OutOfMemoryError.
