"According to the versions of the binutils packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - An issue was discovered in cplus-dem.c in GNU
    libiberty, as distributed in GNU Binutils 2.29 and
    2.30. Stack Exhaustion occurs in the C++ demangling
    functions provided by libiberty, and there are
    recursive stack frames: demangle_nested_args,
    demangle_args, do_arg, and do_type.(CVE-2018-9138)

  - The Binary File Descriptor (BFD) library (aka libbfd),
    as distributed in GNU Binutils 2.28, is vulnerable to
    an invalid write of size 8 because of missing a
    malloc() return-value check to see if memory had
    actually been allocated in the
    _bfd_generic_get_section_contents function. This
    vulnerability causes programs that conduct an analysis
    of binary programs using the libbfd library, such as
    objcopy, to crash.(CVE-2017-8395)

  - _bfd_elf_slurp_version_tables in elf.c in the Binary
    File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.29, allows remote
    attackers to cause a denial of service (excessive
    memory allocation and application crash) via a crafted
    ELF file.(CVE-2017-14938)

  - 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)

  - elflink.c in the Binary File Descriptor (BFD) library
    (aka libbfd), as distributed in GNU Binutils 2.28, has
    a 'member access within null pointer' undefined
    behavior issue, which might allow remote attackers to
    cause a denial of service (application crash) or
    possibly have unspecified other impact via an 'int
    main() {return 0}' program.(CVE-2017-7614)

  - A heap-based buffer over-read issue was discovered in
    the function sec_merge_hash_lookup in merge.c in the
    Binary File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.31, because
    _bfd_add_merge_section mishandles section merges when
    size is not a multiple of entsize. A specially crafted
    ELF allows remote attackers to cause a denial of
    service, as demonstrated by ld.(CVE-2018-18605)

  - An issue was discovered in the merge_strings function
    in merge.c in the Binary File Descriptor (BFD) library
    (aka libbfd), as distributed in GNU Binutils 2.31.
    There is a NULL pointer dereference in
    _bfd_add_merge_section when attempting to merge
    sections with large alignments. A specially crafted ELF
    allows remote attackers to cause a denial of service,
    as demonstrated by ld.(CVE-2018-18606)

  - An issue was discovered in elf_link_input_bfd in
    elflink.c in the Binary File Descriptor (BFD) library
    (aka libbfd), as distributed in GNU Binutils 2.31.
    There is a NULL pointer dereference in
    elf_link_input_bfd when used for finding STT_TLS
    symbols without any TLS section. A specially crafted
    ELF allows remote attackers to cause a denial of
    service, as demonstrated by ld.(CVE-2018-18607)

  - The _bfd_generic_read_minisymbols function in syms.c in
    the Binary File Descriptor (BFD) library (aka libbfd),
    as distributed in GNU Binutils 2.31, has a memory leak
    via a crafted ELF file, leading to a denial of service
    (memory consumption), as demonstrated by
    nm.(CVE-2018-20002)

  - The decode_line_info function in dwarf2.c in the Binary
    File Descriptor (BFD) library (aka libbfd), as
    distributed in GNU Binutils 2.29, allows remote
    attackers to cause a denial of service (read_1_byte
    heap-based buffer over-read and application crash) via
    a crafted ELF file.(CVE-2017-14128)

  - decode_line_info in dwarf2.c in the Binary File
    Descriptor (BFD) library (aka libbfd), as distributed
    in GNU Binutils 2.29, mishandles a length calculation,
    which allows remote attackers to cause a denial of
    service (heap-based buffer over-read and application
    crash) via a crafted ELF file, related to
    read_1_byte.(CVE-2017-14939)

  - An issue was discovered in the Binary File Descriptor
    (BFD) library (aka libbfd), as distributed in GNU
    Binutils 2.32. It is an out-of-bounds read leading to a
    SEGV in bfd_getl32 in libbfd.c, when called from
    pex64_get_runtime_function in
    pei-x86_64.c.(CVE-2019-9074)

  - The Binary File Descriptor (BFD) library (aka libbfd),
    as distributed in GNU Binutils 2.28, has an invalid
    read (of size 8) because the code to emit relocs
    (bfd_elf_final_link function in bfd/elflink.c) does not
    check the format of the input file before trying to
    read the ELF reloc section header. The vulnerability
    leads to a GNU linker (ld) program
    crash.(CVE-2017-7299)

  - The setup_group function in elf.c in the Binary File
    Descriptor (BFD) library (aka libbfd), as distributed
    in GNU Binutils 2.29, allows remote attackers to cause
    a denial of service (NULL pointer dereference and
    application crash) via a group section that is too
    small.(CVE-2017-13710)

    string offsets while loading symbols, leading to a GNU
    linker (ld) program crash.(CVE-2017-7300)

  - The Binary File Descriptor (BFD) library (aka libbfd),
    as distributed in GNU Binutils 2.28, has an
    aout_link_add_symbols function in bfd/aoutx.h that has
    an off-by-one vulnerability because it does not
    carefully check the string offset. The vulnerability
    could lead to a GNU linker (ld) program
    crash.(CVE-2017-7301)

  - GNU binutils gold gold v1.11-v1.16 (GNU binutils
    v2.21-v2.31.1) is affected by: Improper Input
    Validation, Signed/Unsigned Comparison, Out-of-bounds
    Read. The impact is: Denial of service. The component
    is: gold/fileread.cc:497, elfcpp/elfcpp_file.h:644. The
    attack vector is: An ELF file with an invalid e_shoff
    header field must be opened.(CVE-2019-1010204)
