[3.5] avahi: Multicast DNS responds to unicast queries outside of local network (CVE-2017-6519)
avahi-daemon in Avahi through 0.6.32 inadvertently responds to IPv6
unicast queries with source addresses
that are not on-link, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially
sensitive information via port-5353 UDP packets. NOTE: this may overlap CVE-2015-2809.
