I get this message when using wifi inspector from advast: CVE-2017-14491. Type is DNS port 53. It is telling me to upgrade firmware for Arris TG1682G router modem. Researched this and chatted with xfinity but they say there router is good it must be my side. Any help and futher knowledge on this would be great.
The DNSmasq heap buffer overflow exploit? The Comcast gateways aren't vulnerable, because the DNS settings are hard coded into them and can't be altered. There's been numerous posts about this issue in the Internet Security subforum.
