    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
