commit 06614111d1be94b43ea8dd83805184d4e177bcea
Author: Nick Clifton <nickc@redhat.com>
Date:   Mon Dec 1 16:43:46 2014 +0000

    More fixes for memory access violations exposed by fuzzed binaries.
    
    	PR binutils/17512
    	* dwarf.h (struct dwarf_section): Add user_data field.
    	* dwarf.c (frame_need_space): Check for an over large register
    	number.
    	(display_debug_frames): Check the return value from
    	frame_need_space.  Check for a CFA expression that is so long the
    	start address wraps around.
    	(debug_displays): Initialise the user_data field.
    	* objdump.c (load_specific_debug_section): Save the BFD section
    	pointer in the user_data field of the dwarf_section structure.
    	(free_debug_section): Update BFD section data when freeing section
    	contents.
    	* readelf.c (load_specific_debug_section): Initialise the
    	user_data field.
    
    	* archive.c (do_slurp_coff_armap): Add range checks to prevent
    	running off the end of the string table.
    	* compress.c (bfd_get_full_section_contents): Return a NULL
    	pointer for zero sized sections.  Do not attempt to copy a buffer
    	onto itself.
    	* elf-attrs.c (_bfd_elf_parse_attributes): Check for an empty
    	header.  Add range checks to avoid running off the end of the
    	section.
    	* elf.c (bfd_elf_get_str_section): Seek before allocating so that
    	if the seek fails, no memory is allocated.
    	(bfd_elf_string_from_elf_section): Do not allocate a string from a
    	non string section.  It only leads to trouble later on.
    	(_bfd_elf_print_private_bfd_data): Check for there being too
    	little external dynamic data.
    	(bfd_section_from_shdr): Replace assertion with a failure mode.
    	(bfd_section_from_shdr): When walking a loaded group section use
    	the internal structure size, not the external size.  Check for the
    	group section being empty.
    	* elf32-i386.c (elf_i386_rtype_to_howto): Replace assertion with a
    	failure mode.
    	* elfcode.h (elf_slurp_reloc_table): Likewise.
    	* reloc.c (bfd_perform_relocation): Avoid seg-fault if the howto
    	parameter is NULL.
