Título:	RedHat Security Advisory RHSA-2010:0528
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2010:0528. 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. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2010-0528.html http://www.redhat.com/security/updates/classification/#moderate Risk factor : High CVSS Score: 7.8
