EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - A vulnerability was found in dnsmasq before version
    2.81, where the memory leak allows remote attackers to
    cause a denial of service (memory consumption) via
    vectors involving DHCP response
    creation.(CVE-2019-14834)

  - A vulnerability was found in Dnsmasq's implementation
    of DNSSEC. Wildcard synthesized NSEC records could be
    improperly interpreted to prove the non-existence of
    hostnames that actually exist.(CVE-2017-15107)

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.");
