Synopsis
The remote CentOS host is missing one or more security updates.Description
Updated avahi packages that fix a security issue are now available for Red Hat Enterprise Linux 5.This update has been rated as having moderate security impact by the Red Hat Security Response Team.
Avahi is an implementation of the DNS Service Discovery and Multicast DNS specifications for Zeroconf 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, see printers to print to, and find shared files on other computers.
Hugo Dias discovered a denial of service flaw in avahi-daemon. A remote attacker on the same local area network (LAN) could send a specially crafted mDNS (Multicast DNS) packet that would cause avahi-daemon to exit unexpectedly due to a failed assertion check.
(CVE-2008-5081)
All users are advised to upgrade to these updated packages, which contain a backported patch which resolves this issue. After installing the update, avahi-daemon will be restarted automatically.
