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

  - The process_version_sections function in readelf.c in
    GNU Binutils 2.29 allows attackers to cause a denial of
    service (Integer Overflow, and hang because of a
    time-consuming loop) or possibly have unspecified other
    impact via a crafted binary file with invalid values of
    ent.vn_next, during 'readelf -a'
    execution.(CVE-2017-14333)

  - dwarf1.c in the Binary File Descriptor (BFD) library
    (aka libbfd), as distributed in GNU Binutils 2.29,
    mishandles pointers, which allows remote attackers to
    cause a denial of service (application crash) or
    possibly have unspecified other impact via a crafted
    ELF file, related to parse_die and parse_line_table, as
    demonstrated by a parse_die heap-based buffer
    over-read.(CVE-2017-15020)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
