  - An information exposure vulnerability has been found in
    NetworkManager when dnsmasq is used in DNS processing
    mode. An attacker in control of a DNS server could
    receive DNS queries even though a Virtual Private
    Network (VPN) was configured on the vulnerable
    machine.(CVE-2018-1000135)

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.");
