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 ofCPU 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.
