    Fix invalid memory access attempting to read the compression header of a
too-small compressed section.

        PR binutils/21149
        * readelf.c (get_compression_header): Add size parameter.  Check
        size against sizeof compression header before attempting to
        extract the header.
        (process_section_headers): Pass size to get_compression_header.
        (dump_section_as_strings): Likewise.
        (dump_section_as_bytes): Likewise.
