It was found that avahi responds to unicast queries coming from outside of local network which may cause an information leak, such as disclosing the device type/model that responds to the request or the operating system. The mDNS response may also be used to amplify denial of service attacks against other networks as the response size is greater than the size of request (CVE-2017-6519).
