"From Red Hat Security Advisory 2010:0945 :

Updated quagga packages that fix two security issues are now available
for Red Hat Enterprise Linux 6.

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.

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 6 it is not possible to exploit
CVE-2010-2948 to run arbitrary code as the overflow is blocked by
FORTIFY_SOURCE.

A NULL pointer dereference flaw was found in the way the Quagga bgpd
daemon parsed the paths of autonomous systems (AS). A configured BGP
peer could crash bgpd on a target system via a specially crafted BGP
message. (CVE-2010-2949)

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."
