  "message": "Sanity check elf_sym_hashes indexing\n\nI\u0027m a little surprised we haven\u0027t already had fuzzing reports of\nindexing off the end of sym_hashes.  The idea here is to preempt such\nbugs.  One wrinkle is that ppc64 can\u0027t leave a zero symtab_hdr when\nsetting up sym_hashes for the fake stub bfd.\n\n\t* elf-bfd.h (struct elf_reloc_cookie): Add \"num_sym\".\n\t(_bfd_elf_get_link_hash_entry): Update declaration.\n\t* elf-eh-frame.c (find_merged_cie): Sanity check reloc symbol\n\tindex.\n\t* elf64-ppc.c (use_global_in_relocs): Fake up symtab_hdr for\n\tstub bfd.\n\t* elflink.c (_bfd_elf_get_link_hash_entry): Add \"num_sym\"\n\tparam.  Check symndx against it.  Update all calls.\n\t(set_symbol_value): Add \"num_sym\" param and update all calls.\n\t(elf_link_input_bfd): Add \"num_syms\" var and use for above.\n\t(init_reloc_cookie): Set \"cookie-\u003enum_syms\".\n\t* elf64-x86-64.c (elf_x86_64_scan_relocs): Pass symtab number\n\tof entries to _bfd_elf_get_link_hash_entry.\n\t* elfxx-x86.c (_bfd_x86_elf_check_relocs): Likewise.\n\t(_bfd_x86_elf_link_relax_section): Likewise.\n",
