"From Red Hat Security Advisory 2011:0406 :

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 denial of service flaw was found in the way the Quagga bgpd daemon
processed certain route metrics information. A BGP message with a
specially crafted path limit attribute would cause the bgpd daemon to
reset its session with the peer through which this message was
received. (CVE-2010-1675)

A NULL pointer dereference flaw was found in the way the Quagga bgpd
daemon processed malformed route extended communities attributes. A
configured BGP peer could crash bgpd on a target system via a
specially crafted BGP message. (CVE-2010-1674)

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."
