Quagga is a free software implementation of several TCP/IP based routing protocols including RIP, OSPF and BGP.
Quagga was found to contain a flaw in the way it interprets RIP REQUEST messages. The RIP daemon in Quagga would respond to REQUEST messages for either versions of RIP that were disabled or when authentication is enabled, disclosing local network information to a remote entity. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-2223 to this issue.
Quagga was found to have a route injection flaw when interpreting RIPv1 RESPONSE packets while RIPv2 authentication was enabled. A remote attacker could use this flaw to possibly inject arbitrary route information into the RIP routing tables. Configurations with only RIPv2 specified are not affected by this flaw. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-2224 to this issue.
Quagga's telnet interface was found to contain a denial of service vulnerability. A malicious user could cause excessive CPU resource utilization via a malformed "sh" command if they could connect to the telnet interface. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-2276 to this issue.
No Avaya System products are vulnerable, as quagga is not installed by default.
More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendors guidance:
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya Interactive Response(IR) | All | None | Depending on the Operating System provided by customers, the affected packages may be installed on the underlying Operating System supporting the IR application. The IR application does not require the software described in this advisory. |
| CVLAN | All | None | Depending on the Operating System provided by customers, the affected packages may be installed on the underlying Operating System supporting the CVLAN application. The CVLAN application does not require the software described in this advisory. |
| Avaya Integrated Management Suite(IMS) | All | None | Depending on the Operating System provided by customers, the affected packages may be installed on the underlying Operating System supporting the IMS application. The IMS application does not require the software described in this advisory. |
Recommended Actions:
Avaya recommends that customers follow
recommended actions supplied by the Operating System vendor (e.g.
RedHat
Linux) or remove the affected packages.
