Security Fix(es):
* binutils: Improper bounds check in coffgen.c:coff_pointerize_aux() allows for denial of service when parsing a crafted COFF file (CVE-2018-7208)
* binutils: integer overflow via an ELF file with corrupt dwarf1 debug information in libbfd library (CVE-2018-7568)
* 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: Integer overflow in the display_debug_ranges function resulting in crash (CVE-2018-7643)
* 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 service via crafted file (CVE-2018-10372)
* binutils: NULL pointer dereference in dwarf2.c:concat_filename() allows for denial of service via crafted file (CVE-2018-10373)
* binutils: out of bounds memory write in peXXigen.c files (CVE-2018-10534)
* binutils: NULL pointer dereference in elf.c (CVE-2018-10535)
* binutils: Uncontrolled Resource Consumption in execution of nm (CVE-2018-13033)
