Synopsis:	Moderate: quagga security update
Issue date:	2011-03-31
CVE Names:	CVE-2010-1674 CVE-2010-1675

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)

After installing the updated packages, the bgpd daemon must be restarted
for the update to take effect.
