3. Description:

The binutils packages provide a collection of binary utilities for the
manipulation of object code in various object file formats. It includes the
ar, as, gprof, ld, nm, objcopy, objdump, ranlib, readelf, size, strings,
strip, and addr2line utilities.

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)
