Synopsis:	Moderate: quagga security update
Issue date:	2010-10-20
CVE Names:	CVE-2007-4826 CVE-2010-2948

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 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)

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