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 corrupted checksums. An attacker on the
local network could use this flaw to cause avahi-daemon on a target system
to exit unexpectedly via specially-crafted mDNS packets. (CVE-2010-2244)
A flaw was found in the way avahi-daemon processed incoming unicast mDNS
messages. If the mDNS reflector were enabled on a system, an attacker on
the local network could send a specially-crafted unicast mDNS message to
that system, resulting in its avahi-daemon flooding the network with a
multicast packet storm, and consuming a large amount of CPU. Note: The mDNS
reflector is disabled by default. (CVE-2009-0758)
All users are advised to upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the update,
avahi-daemon will be restarted automatically.");
