"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has binutils packages installed that are affected
by multiple vulnerabilities:

  - The Binary File Descriptor (BFD) library (aka libbfd),
    as distributed in GNU Binutils 2.30, allows remote
    attackers to cause a denial of service (excessive memory
    allocation and application crash) via a crafted ELF
    file, as demonstrated by _bfd_elf_parse_attributes in
    elf-attrs.c and bfd_malloc in libbfd.c. This can occur
    during execution of nm. (CVE-2018-13033)

  - The _bfd_XX_bfd_copy_private_bfd_data_common function in
    peXXigen.c in the Binary File Descriptor (BFD) library
    (aka libbfd), as distributed in GNU Binutils 2.30,
    processes a negative Data Directory size with an
    unbounded loop that increases the value of
    (external_IMAGE_DEBUG_DIRECTORY) *edd so that the
    address exceeds 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. (CVE-2018-10534)

  - The ignore_section_sym function in elf.c in the Binary
    File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.30, does not validate the
    output_section pointer in the case of a symtab entry
    with a SECTION type that has a 0 value, which allows
    remote attackers to cause a denial of service (NULL
    pointer dereference and application crash) via a crafted
    file, as demonstrated by objcopy. (CVE-2018-10535)

  - process_cu_tu_index in dwarf.c in GNU Binutils 2.30
    allows remote attackers to cause a denial of service
    (heap-based buffer over-read and application crash) via
    a crafted binary file, as demonstrated by readelf.
    (CVE-2018-10372)

  - concat_filename in dwarf2.c in the Binary File
    Descriptor (BFD) library (aka libbfd), as distributed in
    GNU Binutils 2.30, allows remote attackers to cause a
    denial of service (NULL pointer dereference and
    application crash) via a crafted binary file, as
    demonstrated by nm-new. (CVE-2018-10373)

  - The display_debug_ranges function in dwarf.c in GNU
    Binutils 2.30 allows 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. (CVE-2018-7643)

  - An integer wraparound has been discovered in the Binary
    File Descriptor (BFD) library distributed in GNU
    Binutils up to version 2.30. An attacker could cause a
    crash by providing an ELF file with corrupted DWARF
    debug information. (CVE-2018-7568, CVE-2018-7569)

  - The swap_std_reloc_in function in aoutx.h in the Binary
    File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.30, allows 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. (CVE-2018-7642)

  - The bfd_section_from_shdr function in elf.c in the
    Binary File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.30, allows remote
    attackers to cause a denial of service (segmentation
    fault) via a large attribute section. (CVE-2018-8945)

  - In the coff_pointerize_aux function in coffgen.c in the
    Binary File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.30, an index is not
    validated, which allows remote attackers to cause a
    denial of service (segmentation fault) or possibly have
    unspecified other impact via a crafted file, as
    demonstrated by objcopy of a COFF object.
