CVE-2011-1002
avahi-core/socket.c in avahi-daemon in Avahi before 0.6.29 allows
remote attackers to cause a denial of service (infinite loop) via an
empty (1) IPv4 or (2) IPv6 UDP packet to port 5353.  NOTE: this
vulnerability exists because of an incorrect fix for CVE-2010-2244.

CVE-2010-2244
The AvahiDnsPacket function in avahi-core/socket.c in avahi-daemon in
Avahi 0.6.16 and 0.6.25 allows remote attackers to cause a denial of
service (assertion failure and daemon exit) via a DNS packet with an
invalid checksum followed by a DNS packet with a valid checksum, a
different vulnerability than CVE-2008-5081.";
