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

  - A denial of service flaw was found in the way BIND
    handled query responses when both DNS64 and RPZ were
    used. A remote attacker could use this flaw to make
    named exit unexpectedly with an assertion failure or a
    null pointer dereference via a specially crafted DNS
    response. (CVE-2017-3135)

  - A denial of service flaw was found in the way BIND
    processed a response to an ANY query. A remote attacker
    could use this flaw to make named exit unexpectedly
    with an assertion failure via a specially crafted DNS
    response. (CVE-2016-9131)

  - A denial of service flaw was found in the way BIND
    handled a query response containing inconsistent DNSSEC
    information. A remote attacker could use this flaw to
    make named exit unexpectedly with an assertion failure
    via a specially crafted DNS response. (CVE-2016-9147)

  - A denial of service flaw was found in the way BIND
    handled an unusually-formed DS record response. A
    remote attacker could use this flaw to make named exit
    unexpectedly with an assertion failure via a specially
    crafted DNS response. (CVE-2016-9444)

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.");
