1. Summary:

Updated zebra packages that fix several security vulnerabilities are now
available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64

3. Problem description:

GNU Zebra is a free software that manages TCP/IP based routing protocol.

An information disclosure flaw was found in the way GNU Zebra interprets
RIP REQUEST packets. RIPd in GNU Zebra will respond to RIP REQUEST packets
for RIP versions that have been disabled or that have authentication
enabled, allowing a remote attacker to acquire information about the local
network. (CVE-2006-2223)

A route injection flaw was found in the way GNU Zebra interprets RIPv1
RESPONSE packets when RIPv2 authentication is enabled. It is possible for a
remote attacker to inject arbitrary route information into the RIPd routing
tables. This issue does not affect GNU Zebra configurations where only
RIPv2 is specified. (CVE-2006-2224)

A denial of service flaw was found in GNU Zebra's telnet interface. If an
attacker is able to connect to the GNU Zebra telnet interface, it is
possible to cause GNU Zebra to consume vast quantities of CPU resources by
issuing a malformed 'sh' command. (CVE-2006-2276)

Users of GNU Zebra should upgrade to these updated packages, which contain
backported patches that correct these issues.

4. Solution:

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

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

192757 - CVE-2006-2224 zebra RIPd route injection
192758 - CVE-2006-2276 zebra locks with command sh ip bgp
192759 - CVE-2006-2223 zebra RIPd information disclosure
