=====================================================================
                   Red Hat Security Advisory

Synopsis:          Moderate: quagga security update
Advisory ID:       RHSA-2010:0785-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0785.html
Issue date:        2010-10-20
CVE Names:         CVE-2007-4826 CVE-2010-2948 
=====================================================================

1. Summary:

Updated quagga packages that fix multiple security issues are now available

3. Description:

Quagga is a TCP/IP based routing software suite. The Quagga bgpd daemon
implements the BGP (Border Gateway Protocol) routing protocol.

A stack-based buffer overflow flaw was found in the way the Quagga bgpd
daemon processed certain BGP Route Refresh (RR) messages. A configured BGP
peer could send a specially-crafted BGP message, causing bgpd on a target
system to crash or, possibly, execute arbitrary code with the privileges of
the user running bgpd. (CVE-2010-2948)

Note: On Red Hat Enterprise Linux 5 it is not possible to exploit
CVE-2010-2948 to run arbitrary code as the overflow is blocked by
FORTIFY_SOURCE.

Multiple NULL pointer dereference flaws were found in the way the Quagga
bgpd daemon processed certain specially-crafted BGP messages. A configured
BGP peer could crash bgpd on a target system via specially-crafted BGP
messages. (CVE-2007-4826)

Users of quagga should upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the updated
packages, the bgpd daemon must be restarted for the update to take effect.

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
