dnsmasq is vulnerable to denial of service(DoS) attacks. A remote user could send specially crafted DNS packets to trigger an integer underflow and subsequent buffer over-read error in the EDNS0 code and cause the target service to crash. This issue only affects configurations using one of the options: add-mac, add-cpe-id, or add-subnet.
