Detail
| Problem Description: 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 |

Open Source Vulnerability Database (OSVDB)
| Id | Description |
|---|---|
| 25245 | Quagga bgpd Telnet Interface Local DoS Quagga contains a flaw that may allow a local denial of service. The issue is triggered when certain crafted input is passed to the 'sh ip bgp community' command, and will result in loss of availability for the platform by using all up CPU resources. |
| 25225 | Quagga RIPd RIPv1 RESPONSE Packet Route Injection Quagga contains a flaw that may allow an unauthenticated attacker to inject RIP routes into the 'RIPd' service. The issue is triggered when the service is configured with MD5 authentication but no specific RIP version in the configuration file. It is then possible to send unauthenticated RIPv1 'RESPONSE' packets that will be accepted by the service, causing a manipulation of the RIP routing table and resulting in a loss of integrity. |
| 25224 | Quagga RIPd RIPv1 Request Routing Table Disclosure Quagga contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a RIPv1 'SEND UPDATE' request is sent to the 'RIPd' service, even when it is configured to support RIPv2 only. This will also happen when the RIPv2-only service is configued to work with MD5 authentication. The vulnerability will disclose the service's RIP routing table, resulting in a loss of confidentiality. |
