     (bsc#1086608)
   - CVE-2018-7643: The display_debug_ranges function allowed remote
     attackers to cause a denial of service (integer overflow and application
     crash) or possibly have unspecified other impact via a crafted ELF file,
     as demonstrated by
     objdump (bsc#1086784)
   - CVE-2018-7642: The swap_std_reloc_in function in the Binary File
     Descriptor (BFD) library (aka libbfd) allowed remote attackers to cause
     a denial of service (aout_32_swap_std_reloc_out NULL pointer dereference
     and application crash) via a crafted ELF file, as demonstrated by
     objcopy (bsc#1086786)
   - CVE-2018-7568: The parse_die function in the Binary File Descriptor
     (BFD) library (aka libbfd) allowed remote attackers to cause a denial of
     service (integer overflow and application crash) via an ELF file with
     corrupt dwarf1 debug information, as demonstrated by nm (bsc#1086788)
   - CVE-2018-10373: concat_filename in the Binary File Descriptor (BFD)
     library (aka libbfd) allowed remote attackers to cause a denial of
     service (NULL pointer dereference and application crash) via a crafted
     binary file, as demonstrated by nm-new (bsc#1090997)

   - CVE-2018-10535: The ignore_section_sym function in the Binary File
     Descriptor (BFD) library (aka libbfd) did not validate the
     output_section pointer in the case of a symtab entry with a "SECTION"
     type that has a "0" value, which allowed remote attackers to cause a
     denial of service (NULL pointer dereference and application crash) via a
     crafted file, as demonstrated by objcopy (bsc#1091365)
   - CVE-2018-10534: The _bfd_XX_bfd_copy_private_bfd_data_common function in
     the Binary File Descriptor (BFD) library (aka libbfd) processesed a
     negative Data Directory size with an unbounded loop that increased the
     value of (external_IMAGE_DEBUG_DIRECTORY) *edd so that the address
     exceeded its own memory region, resulting in an out-of-bounds memory
     write, as demonstrated by
     objcopy copying private info with
      _bfd_pex64_bfd_copy_private_bfd_data_common in pex64igen.c (bsc#1091368)

   These non-security issues were fixed:

   - The AArch64 port now supports showing disassembly notes which are
     emitted when inconsistencies are found with the instruction that may
     result in the instruction being invalid.  These can be turned on with
     the option -M notes to objdump.
   - The AArch64 port now emits warnings when a combination of an instruction
     and a named register could be invalid.
   - Added O modifier to ar to display member offsets inside an archive
   - The ADR and ADRL pseudo-instructions supported by the ARM assembler now
     only set the bottom bit of the address of thumb function symbols if the
     -mthumb-interwork command line option is active.
   - Add --generate-missing-build-notes=[yes|no] option to create (or not)
     GNU Build Attribute notes if none are present in the input sources.  Add
     a
     --enable-generate-build-notes=[yes|no] configure time option to set the
      default behaviour.  Set the default if the configure option is not used
      to "no".
   - Remove -mold-gcc command-line option for x86 targets.
   - Add -O[2|s] command-line options to x86 assembler to enable alternate
     shorter instruction encoding.
   - Add support for .nops directive.  It is currently supported only for x86
     targets.
   - Speed up direct linking with DLLs for Cygwin and Mingw targets.
   - Add a configure option --enable-separate-code to decide whether
     -z separate-code should be enabled in ELF linker by default.  Default to
      yes for Linux/x86 targets.  Note that -z separate-code can increase
      disk and memory size.
   - RISC-V: Fix symbol address problem with versioned symbols
   - Restore riscv64-elf cross prefix via symlinks
   - Fix pacemaker libqb problem with section start/stop symbols
   - RISC-V: Don't enable relaxation in relocatable link
   - Prevent linking faiures on i386 with assertion (bsc#1085784)
   - Fix symbol size bug when relaxation deletes bytes
   - Add --debug-dump=links option to readelf and --dwarf=links option to
     objdump which displays the contents of any .gnu_debuglink or
     .gnu_debugaltlink sections. Add a --debug-dump=follow-links option to
     readelf and a --dwarf=follow-links
     option to objdump which causes indirect links into separate debug info
      files to be followed when dumping other DWARF sections.
   - Add support for loaction views in DWARF debug line information.
   - Add -z separate-code to generate separate code PT_LOAD segment.
   - Add "-z undefs" command line option as the inverse of the "-z defs"
     option.
   - Add -z globalaudit command line option to force audit libraries to be
     run for every dynamic object loaded by an executable - provided that the
     loader supports this functionality.
   - Tighten linker script grammar around file name specifiers to prevent the
     use
     of SORT_BY_ALIGNMENT and SORT_BY_INIT_PRIORITY on filenames.  These
      would previously be accepted but had no effect.
   - The EXCLUDE_FILE directive can now be placed within any SORT_* directive
     within input section lists.
   - Fix linker relaxation with --wrap
