A vulnerability was discovered and corrected in avahi:

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 (CVE-2010-2244).
