The remote host is missing an update for the Huawei EulerOS 'dnsmasq' package(s) announced via the EulerOS-SA-2020-1776 advisory. A vulnerability in dnsmasq before version 2.81 allows remote attackers to cause a denial of service via vectors involving DHCP response creation. Another vulnerability involves DNSSEC implementation allowing improper interpretation of wildcard synthesized NSEC records
