+  <background>
+    <p>
+    Avahi is a system that facilitates service discovery on a local
+    network.

+  <description>
+    <p>
+    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.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    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.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Avahi users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=net-dns/avahi-0.6.24-r2"</code>
