  - binutils: Address violation in aarch64_ext_ldst_reglist function when disassembling corrupt aarch64 binary
    (CVE-2017-9756)

  - The elf_read_notesfunction in bfd/elf.c in GNU Binutils 2.29 allows remote attackers to cause a denial of
    service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted
    binary file. (CVE-2017-12799)

  - The score_opcodes function in opcodes/score7-dis.c in GNU Binutils 2.28 allows remote attackers to cause a
    denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a
    crafted binary file, as demonstrated by mishandling of this file during objdump -D execution.
    (CVE-2017-9742)

  - The print_insn_score32 function in opcodes/score7-dis.c:552 in GNU Binutils 2.28 allows remote attackers
    to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other
    impact via a crafted binary file, as demonstrated by mishandling of this file during objdump -D
    execution. (CVE-2017-9743)

  - The sh_elf_set_mach_from_flags function in bfd/elf32-sh.c in the Binary File Descriptor (BFD) library (aka
    libbfd), as distributed in GNU Binutils 2.28, allows remote attackers to cause a denial of service (buffer
    overflow and application crash) or possibly have unspecified other impact via a crafted binary file, as
    demonstrated by mishandling of this file during objdump -D execution. (CVE-2017-9744)

  - The _bfd_vms_slurp_etir function in bfd/vms-alpha.c in the Binary File Descriptor (BFD) library (aka
    libbfd), as distributed in GNU Binutils 2.28, allows remote attackers to cause a denial of service (buffer
    overflow and application crash) or possibly have unspecified other impact via a crafted binary file, as
    demonstrated by mishandling of this file during objdump -D execution. (CVE-2017-9745)

  - The disassemble_bytes function in objdump.c in GNU Binutils 2.28 allows remote attackers to cause a denial
    of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted
    binary file, as demonstrated by mishandling of rae insns printing for this file during objdump -D
    execution. (CVE-2017-9746)

  - The ieee_archive_p function in bfd/ieee.c in the Binary File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.28, might allow remote attackers to cause a denial of service (buffer
    overflow and application crash) or possibly have unspecified other impact via a crafted binary file, as
    demonstrated by mishandling of this file during objdump -D execution. NOTE: this may be related to a
    compiler bug. (CVE-2017-9747)

  - The ieee_object_p function in bfd/ieee.c in the Binary File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.28, might allow remote attackers to cause a denial of service (buffer
    overflow and application crash) or possibly have unspecified other impact via a crafted binary file, as
    demonstrated by mishandling of this file during objdump -D execution. NOTE: this may be related to a
    compiler bug. (CVE-2017-9748)

  - The *regs* macros in opcodes/bfin-dis.c in GNU Binutils 2.28 allow remote attackers to cause a denial of
    service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted
    binary file, as demonstrated by mishandling of this file during objdump -D execution. (CVE-2017-9749)

  - opcodes/rx-decode.opc in GNU Binutils 2.28 lacks bounds checks for certain scale arrays, which allows
    remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have
    unspecified other impact via a crafted binary file, as demonstrated by mishandling of this file during
    objdump -D execution. (CVE-2017-9750)

  - opcodes/rl78-decode.opc in GNU Binutils 2.28 has an unbounded GETBYTE macro, which allows remote attackers
    to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other
    impact via a crafted binary file, as demonstrated by mishandling of this file during objdump -D
    execution. (CVE-2017-9751)

  - bfd/vms-alpha.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils
    2.28, allows remote attackers to cause a denial of service (buffer overflow and application crash) or
    possibly have unspecified other impact via a crafted binary file, as demonstrated by mishandling of this
    file in the _bfd_vms_get_value and _bfd_vms_slurp_etir functions during objdump -D execution.
    (CVE-2017-9752)

  - The versados_mkobject function in bfd/versados.c in the Binary File Descriptor (BFD) library (aka libbfd),
    as distributed in GNU Binutils 2.28, does not initialize a certain data structure, which allows remote
    attackers to cause a denial of service (buffer overflow and application crash) or possibly have
    unspecified other impact via a crafted binary file, as demonstrated by mishandling of this file during
    objdump -D execution. (CVE-2017-9753)

  - The process_otr function in bfd/versados.c in the Binary File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.28, does not validate a certain offset, which allows remote attackers to
    cause a denial of service (buffer overflow and application crash) or possibly have unspecified other
    impact via a crafted binary file, as demonstrated by mishandling of this file during objdump -D
    execution. (CVE-2017-9754)

  - opcodes/i386-dis.c in GNU Binutils 2.28 does not consider the number of registers for bnd mode, which
    allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly
    have unspecified other impact via a crafted binary file, as demonstrated by mishandling of this file
    during objdump -D execution. (CVE-2017-9755)

  - The getvalue function in tekhex.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed
    in GNU Binutils 2.28, allows remote attackers to cause a denial of service (stack-based buffer over-read
    and application crash) via a crafted tekhex file, as demonstrated by mishandling within the nm program.
    (CVE-2017-9954)

  - The get_build_id function in opncls.c in the Binary File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.28, allows remote attackers to cause a denial of service (heap-based buffer
    over-read and application crash) via a crafted file in which a certain size field is larger than a
    corresponding data field, as demonstrated by mishandling within the objdump program. (CVE-2017-9955)
