Israel-based security consultancy firm JSOF disclosed seven Dnsmasq vulnerabilities today. They can be exploited to launch DNS cache poisoning, remote code execution, and denial-of-service attacks against millions of affected devices. The full number or the name of all companies that use Dnsmaq versions vulnerable to DNSpooq attacks on their devices is not yet known. The first DNS spoofing attack was disclosed by security researcher Dan Kaminsky in 2008 when he showed that DNS software can be used to steal data.
