                   Red Hat Security Advisory

Synopsis:          Moderate: avahi security update
Advisory ID:       RHSA-2010:0528-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0528.html
Issue date:        2010-07-13
CVE Names:         CVE-2009-0758 CVE-2010-2244 
=====================================================================

1. Summary:

Updated avahi packages that fix two security issues are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

488314 - CVE-2009-0758 avahi: remote DoS via legacy unicast mDNS queries
607293 - CVE-2010-2244 avahi: assertion failure after receiving a packet with corrupted checksum
