Summary
The remote host is missing an update for the 'avahi' package(s) announced via the referenced advisory.
Insight
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.
