Vulnerability Assessment Summary
Check for the version of the zebra packages

Detailed Explanation for this Vulnerability Assessment

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.

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, permiting 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.
