Red Hat Security Advisory

Synopsis: Moderate: quagga security update
Advisory ID: RHSA-2012:1258-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1258.html
Issue date: 2012-09-12
CVE Names: CVE-2010-1674 CVE-2011-3323 CVE-2011-3324

=====================================================================

1. Summary:

Updated quagga packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 5.

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:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - 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. The Quagga
ospfd and ospf6d daemons implement the OSPF (Open Shortest Path First)
routing protocol.

A heap-based buffer overflow flaw was found in the way the bgpd daemon
processed malformed Extended Communities path attributes. An attacker 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. The UPDATE message would have to arrive from an explicitly
configured BGP peer, but could have originated elsewhere in the BGP
network. (CVE-2011-3327)

A NULL pointer dereference flaw was found in the way the bgpd daemon
processed malformed route Extended Communities attributes. A configured
BGP peer could crash bgpd on a target system via a specially-crafted BGP
message. (CVE-2010-1674)

A stack-based buffer overflow flaw was found in the way the ospf6d daemon
processed malformed Link State Update packets. An OSPF router could use
this flaw to crash ospf6d on an adjacent router. (CVE-2011-3323)

A flaw was found in the way the ospf6d daemon processed malformed link
state advertisements. An OSPF neighbor could use this flaw to crash
ospf6d on a target system. (CVE-2011-3324)

A flaw was found in the way the ospfd daemon processed malformed Hello
packets. An OSPF neighbor could use this flaw to crash ospfd on a
target system. (CVE-2011-3325)

A flaw was found in the way the ospfd daemon processed malformed link state
advertisements. An OSPF router in the autonomous system could use this flaw
to crash ospfd on a target system. (CVE-2011-3326)

An assertion failure was found in the way the ospfd daemon processed
certain Link State Update packets. An OSPF router could use this flaw to
cause ospfd on an adjacent router to abort. (CVE-2012-0249)

A buffer overflow flaw was found in the way the ospfd daemon processed
certain Link State Update packets. An OSPF router could use this flaw to
crash ospfd on an adjacent router. (CVE-2012-0250)

Red Hat would like to thank CERT-FI for reporting CVE-2011-3327,
CVE-2011-3323, CVE-2011-3324, CVE-2011-3325, and CVE-2011-3326; and the
CERT/CC for reporting CVE-2012-0249 and CVE-2012-0250. CERT-FI acknowledges
Riku Hietamäki, Tuomo Untinen and Jukka Taimisto of the Codenomicon CROSS
project as the original reporters of CVE-2011-3327, CVE-2011-3323,
CVE-2011-3324, CVE-2011-3325, and CVE-2011-3326. The CERT/CC acknowledges
Martin Winter at OpenSourceRouting.org as the original reporter of
CVE-2012-0249 and CVE-2012-0250.

Users of quagga should upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the updated
packages, the bgpd, ospfd, and ospf6d daemons will be restarted
automatically.
