+ Avahi is a system that facilitates service discovery on a local + network. +

+
+ +

+ Rob Leslie reported that the + originates_from_local_legacy_unicast_socket() function in + avahi-core/server.c does not account for the network byte order of a + port number when processing incoming multicast packets, leading to a + multicast packet storm. +

+
+ +

+ A remote attacker could send specially crafted legacy unicast mDNS + query packets to the Avahi daemon, resulting in a Denial of Service due + to network bandwidth and CPU consumption. +

+
+ +

+ There is no known workaround at this time. +

+
+ +

+ All Avahi users should upgrade to the latest version: +

+ + # emerge --sync + # emerge --ask --oneshot --verbose ">=net-dns/avahi-0.6.24-r2" +
