The affected device's DNS service is running an outdated version of the DnsMasq software which is known to have a heap buffer overflow vulnerability. A remote attacker can gain control of your network device and your Internet connection by sending malformed DNS packets to the device. It allows the attacker to intercept connections and perform a traffic hijack, or execute arbitrary code with unrestricted privileges as well as access all important and private data stored on the device -- your device login/password combination, your Wi-Fi password, and your configuration data.
