• 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)
