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

  - A use after free issue exists in the Binary File
    Descriptor (BFD) library (aka libbfd) in GNU Binutils
    2.34 in bfd_hash_lookup, as demonstrated in nm-new,
    that can cause a denial of service via a crafted
    file.(CVE-2020-16592)

  - An issue was discovered in the Binary File Descriptor
    (BFD) library (aka libbfd), as distributed in GNU
    Binutils 2.31. An invalid memory access exists in
    _bfd_stab_section_find_nearest_line in syms.c.
    Attackers could leverage this vulnerability to cause a
    denial of service (application crash) via a crafted ELF
    file.(CVE-2018-17358)

  - 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 2.31. An invalid memory access exists in
    bfd_zalloc in opncls.c. Attackers could leverage this
    vulnerability to cause a denial of service (application
    crash) via a crafted ELF file.(CVE-2018-17359)

  - 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)
