"According to the versions of the binutils package installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - GNU gdb All versions is affected by: Buffer Overflow -
    Out of bound memory access. The impact is: Deny of
    Service, Memory Disclosure, and Possible Code
    Execution. The component is: The main gdb module. The
    attack vector is: Open an ELF for debugging. The fixed
    version is: Not fixed yet.(CVE-2019-1010180)

  - 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)

  - binutils version 2.32 and earlier contains a Integer
    Overflow vulnerability in objdump,
    bfd_get_dynamic_reloc_upper_bound,bfd_canonicalize_dyna
    mic_reloc that can result in Integer overflow trigger
    heap overflow. Successful exploitation allows execution
    of arbitrary code.. This attack appear to be
    exploitable via Local. This vulnerability appears to
    have been fixed in after commit
    3a551c7a1b80fca579461774860574eabfd7f18f.(CVE-2018-1000
    876)

  - 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)

  - 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 Binary File Descriptor
    (BFD) library (aka libbfd), as distributed in GNU
    Binutils 2.31. An invalid memory address dereference
    was discovered in read_reloc in reloc.c. The
    vulnerability causes a segmentation fault and
    application crash, which leads to denial of service, as
    demonstrated by objdump, because of missing
    _bfd_clear_contents bounds checking.(CVE-2018-18309)

  - An issue was discovered in the Binary File Descriptor
    (BFD) library (aka libbfd), as distributed in GNU
    Binutils 2.32. It is an integer overflow leading to a
    SEGV in _bfd_dwarf2_find_nearest_line in dwarf2.c, as
    demonstrated by nm.(CVE-2019-17451)

  - find_abstract_instance in dwarf2.c in the Binary File
    Descriptor (BFD) library (aka libbfd), as distributed
    in GNU Binutils 2.32, allows remote attackers to cause
    a denial of service (infinite recursion and application
    crash) via a crafted ELF file.(CVE-2019-17450)

  - An issue was discovered in the Binary File Descriptor
    (BFD) library (aka libbfd), as distributed in GNU
    Binutils 2.32. There is a heap-based buffer over-read
    in _bfd_doprnt in bfd.c because elf_object_p in
    elfcode.h mishandles an e_shstrndx section of type
    SHT_GROUP by omitting a trailing '\0'
    character.(CVE-2019-12972)

  - load_specific_debug_section in objdump.c in GNU
    Binutils through 2.31.1 contains an integer overflow
    vulnerability that can trigger a heap-based buffer
    overflow via a crafted section size.(CVE-2018-20671)
