CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as problematic has been found in Quagga (Network Routing Software). This affects an unknown function. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

bgpd in Quagga before 0.99.9 allows explicitly configured BGP peers to cause a denial of service (crash) via a malformed (1) OPEN message or (2) a COMMUNITY attribute, which triggers a NULL pointer dereference. NOTE: vector 2 only exists when debugging is enabled.

The weakness was published 09/12/2007 by Mu Security with Mu Security (Website). The advisory is shared at lists.debian.org. This vulnerability is uniquely identified as CVE-2007-4826 since 09/11/2007. It is possible to initiate the attack remotely. The successful exploitation requires a authentication. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 68122 (Oracle Linux 4 / 5 : quagga (ELSA-2010-0785)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155592 (Oracle Enterprise Linux Update for Quagga (ELSA-2010-0785)).

Upgrading to version 0.98.5 eliminates this vulnerability. A possible mitigation has been published 4 years after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (36551) and Tenable (68122). Similar entry is available at VDB-54686.
