    readelf: fix out of range subtraction, seg fault from a NULL pointer and
memory exhaustion, all from parsing corrupt binaries.

        * readelf.c (process_dynamic_section): Detect over large section
        offsets in the DT_SYMTAB entry.

        allocation before it happens and print a suitable error message.
