Title:	CentOS Update for avahi CESA-2011:0436 centos5 i386
Summary:	The remote host is missing an update for the 'avahi'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'avahi' package(s) announced via the referenced advisory. Vulnerability 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. Affected Software/OS: avahi on CentOS 5 Solution: Please install the updated packages. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
