===================================================================== Red Hat Security Advisory
Synopsis: Moderate: quagga security update Advisory ID: RHSA-2010:0945-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0945.html Issue date: 2010-12-06 CVE Names: CVE-2010-2948 CVE-2010-2949 =====================================================================
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64
3. Description:
Quagga is a TCP/IP based routing software suite. The Quagga bgpd daemon implements the BGP (Border Gateway Protocol) routing protocol.
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 Red Hat Enterprise 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)
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.
4. Solution:
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):
626783 - CVE-2010-2948 Quagga (bgpd): Stack buffer overflow by processing certain Route-Refresh messages 626795 - CVE-2010-2949 Quagga (bgpd): DoS (crash) while processing certain BGP update AS path messages
