The remote Red Hat host is missing a security update.
Updated zebra packages that fix several security vulnerabilities are
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
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.
