Synopsis

Moderate: quagga security update

Type/Severity

Security Advisory: Moderate

Topic

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.

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.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
