CentOS Update for avahi CESA-2010:0528 centos5 i386

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

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 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.
