More fixes for memory access errors triggered by attemps to examine corrupted binaries.
PR binutils/17512 * dwarf.c (display_block): Do nothing if the block starts after the end of the buffer. (read_and_display_attr_value): Add range checks. (struct Frame_Chunk): Make the ncols and ra fields unsigned. (frame_need_space): Test for an ncols of zero. (read_cie): Fail if the augmentation data extends off the end of the buffer. (display_debug_frames): Add checks for read_cie failing. Add range checks. * coff-h8300.c (rtype2howto): Replace abort with returning a NULL value. * coff-h8500.c (rtype2howto): Likewise. * coff-tic30.c (rtype2howto): Likewise. * coff-z80.c (rtype2howto): Likewise. * coff-z8k.c (rtype2howto): Likewise. * coff-ia64.c (RTYPE2HOWTO): Always return a valid howto. * coff-m68k.c (m68k_rtype2howto): Return a NULL howto if none could be found. * coff-mcore.c (RTYPE2HOWTO): Add range checking. * coff-w65.c (rtype2howto): Likewise. * coff-we32k.c (RTYPE2HOWTO): Likewise. * pe-mips.c (RTYPE2HOWTO): Likewise. * coff-x86_64.c (coff_amd64_reloc): Likewise. Replace abort with an error return. * coffcode.h (coff_slurp_reloc_table): Allow the rel parameter to be unused. * coffgen.c (make_a_section_from_file): Check the length of a section name before testing to see if it is a debug section name. (coff_object_p): Zero out any uninitialised bytes in the opt header. * ecoff.c (_bfd_ecoff_slurp_symbolic_info): Test for the raw source being empty when there are values to be processed. (_bfd_ecoff_slurp_symbol_table): Add range check. * mach-o.c (bfd_mach_o_canonicalize_one_reloc): Likewise. (bfd_mach_o_mangle_sections): Move test for too many sections to before the allocation of the section table. (bfd_mach_o_read_symtab_strtab): If the read fails, free the memory and nullify the symbol pointer. * reloc.c (bfd_generic_get_relocated_section_contents): Add handling of a bfd_reloc_notsupported return value. * versados.c (EDATA): Add range checking. (get_record): Likewise. (process_otr): Check for contents being available before updating them. (versados_canonicalize_reloc): Add range check.
