Vulnerability Assessment Details
Check for the version of the quagga packages
Detailed Explanation for this Vulnerability Assessment
Updated quagga packages that fix several security vulnerabilities are now
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
Quagga manages the TCP/IP based routing protocol. It takes a multi-server
and multi-thread approach to resolve the current complexity of the
An information disclosure flaw was found in the way Quagga interprets RIP
REQUEST packets. RIPd in Quagga 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.
A route injection flaw was found in the way Quagga 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 Quagga configurations where only RIPv2
is specified. (CVE-2006-2224)
A denial of service flaw was found in Quagga's telnet interface. If an
attacker is able to connect to the Quagga telnet interface, it is possible
to cause Quagga to consume vast quantities of CPU resources by issuing a
malformed 'sh' command. (CVE-2006-2276)
Users of Quagga should upgrade to these updated packages, which contain
backported patches that correct these issues.
