Scientific Linux Security Update : quagga on SL6.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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.
