tag_insight = "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.";
