  - binutils: integer underflow or overflow via an ELF file
    with a corrupt DWARF FORM block in libbfd library
    (CVE-2018-7569)

  - binutils: NULL pointer dereference in swap_std_reloc_in
    function in aoutx.h resulting in crash (CVE-2018-7642)

  - binutils: Crash in elf.c:bfd_section_from_shdr() with
    crafted executable (CVE-2018-8945)

  - binutils: Heap-base buffer over-read in
    dwarf.c:process_cu_tu_index() allows for denial of
