Avahi is an implementation of the DNS Service Discovery and Multicast DNS
specifications for Zero Configuration Networking. It facilitates service
discovery on a local network. Avahi and Avahi-aware applications allow you
to plug your computer into a network and, with no configuration, view other
people to chat with, view printers to print to, and find shared files on
other computers.
A flaw was found in the way the Avahi daemon (avahi-daemon) processed
Multicast DNS (mDNS) packets with an empty payload. An attacker on the
local network could use this flaw to cause avahi-daemon on a target system
to enter an infinite loop via an empty mDNS UDP packet. (CVE-2011-1002)
All users are advised to upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing the update,
avahi-daemon will be restarted automatically.
