Otklonjen je sigurnosni problem u radu programskog paketa Avahi. Riječ je o alatu namijenjenom pronalaženju servisa unutar lokalne računalne mreže, poput drugih računala, pisača i dijeljenih direktorija. Ranjivost se javlja u datoteci "avahi-core/socket.c" zbog nepravilne obrade pojedinih paketa poslanih na priključak (eng. port) 5353. Zlonamjerni korisnik može iskoristiti propust za izvođenje napada uskraćivanja usluga (DoS napada). Budući da je dostupna programska nadogradnja, svi se korisnici potiču na njeno korištenje.
