Avahi contains a flaw that may allow a remote denial of service. The issue is triggered when 'avahi-core/socket.c' in 'avahi-daemon' fails to properly handle empty IPv4 or IPv6 UDP packets sent to port 5353, allowing a remote attacker to cause an infinite loop which will trigger a denial of service.
