"According to the versions of the c-ares package installed, the
EulerOS Virtualization installation on the remote host is affected by
the following vulnerabilities :

  - Heap-based buffer overflow in the ares_create_query
    function in c-ares 1.x before 1.12.0 allows remote
    attackers to cause a denial of service (out-of-bounds
    write) or possibly execute arbitrary code via a
    hostname with an escaped trailing dot.(CVE-2016-5180)

  - The c-ares function `ares_parse_naptr_reply()`, which
    is used for parsing NAPTR responses, could be triggered
    to read memory outside of the given input buffer if the
    passed in DNS response packet was crafted in a
    particular way.(CVE-2017-1000381)

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.");
