CVE-2021-40085
An issue was discovered in OpenStack Neutron before 16.4.1, 17.x before 17.2.1, and 18.x before 18.1.1. Authenticated attackers can reconfigure dnsmasq via a crafted extra_dhcp_opts value.
For Debian 9 Stretch, this has now been fixed in version 2:9.1.1-3+deb9u3.
We recommend that you upgrade your neutron packages.
