Synopsis:	Moderate: quagga security update
Issue date:	2010-12-06
CVE Names:	CVE-2010-2948 CVE-2010-2949

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 Scientific 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)

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