	* strip.c (handle_elf): Check for bogus values in sh_link, sh_info,
	st_shndx, e_shstrndx, and SHT_GROUP or SHT_SYMTAB_SHNDX data.
	Don't use assert on input values, instead bail with "illformed" error.

	* elf32_getphdr.c (elfw2(LIBELFBITS,getphdr)): Check if program header
	table fits into object's bounds.
	* elf_getshstrndx.c (elf_getshstrndx): Add elf->start_offset to
	elf->map_address.  Check if first section header fits into object's
	bounds.
	* elf32_getshdr.c (elfw2(LIBELFBITS,getshdr)):
	Check if section header table fits into object's bounds.
	* elf_begin.c (get_shnum): Ensure section headers fits into
	object's bounds.
	(file_read_elf): Make sure scncnt is small enough to allocate both
	ElfXX_Shdr and Elf_Scn array.  Make sure section and program header
	tables fit into object's bounds.  Avoid memory leak on failure.

src/
	* elflint.c (check_hash): Don't check entries beyond end of section.
