Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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.

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.

Solution

Update the affected packages.
