Multiple Quagga remote component vulnerabilities

Overview

Quagga contains five remote component vulnerabilities due to issues when handling BGP, OSPF, and OSPFv3 packets.

Description

CERT-FI reports:

_Quagga is an open source routing software that can handle various routing protocols such as RIP, BGP and OSPF. Five vulnerabilities have been found in the BGP, OSPF and OSPFv3 components of Quagga. The vulnerabilities allow an attacker to cause a denial of service or potentially to execute his own code by sending a specially modified packets to an affected server. Routing messages are typically accepted from the routing peers. Exploiting these vulnerabilities may require an established routing session (BGP peering or OSPF/OSPFv3 adjacency) to the router.

The vulnerability CVE-2011-3327 is related to the extended communities handling in BGP messages. Receiving a malformed BGP update can result in a buffer overflow and disruption of IPv4 routing.

The vulnerability CVE-2011-3326 results from the handling of LSA (Link State Advertisement) states in the OSPF service. Receiving a modified Link State Update message with malicious state information can result in denial of service in IPv4 routing.

The vulnerability CVE-2011-3325 is a denial of service vulnerability related to Hello message handling by the OSPF service. As Hello messages are used to initiate adjacencies, exploiting the vulnerability may be feasible from the same broadcast domain without an established adjacency. A malformed packet may result in denial of service in IPv4 routing.

The vulnerabilities CVE-2011-3324 and CVE-2011-3323 are related to the IPv6 routing protocol (OSPFv3) implemented in ospf6d daemon. Receiving modified Database Description and Link State Update messages, respectively, can result in denial of service in IPv6 routing._

---

Impact

An attacker could exploit these vulnerabilities to cause a denial-of-service crash or may execute arbitrary code on the affected server with the permissions of the Quagga software.

---

Solution

CERT-FI recommends:

Install either the latest version of Quagga (http://www.quagga.net/_) or a fixed version of the software provided by your operating system or application vendor.

The vulnerabilities can be remediated by restricting network access to the routing daemon. Exploiting four of the vulnerabilities require established routing sessions or adjacencies._
