Detailsinfo

A vulnerability was found in Linux Kernel 2.4.34/2.6.20.5 (Operating System). It has been rated as problematic. Affected by this issue is an unknown code block of the file dn_fib.c. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. CVE summarizes:

A typo in Linux kernel 2.6 before 2.6.21-rc6 and 2.4 before 2.4.35 causes RTA_MAX to be used as an array size instead of RTN_MAX, which leads to an "out of bound access" by the (1) dn_fib_props (dn_fib.c, DECNet) and (2) fib_props (fib_semantics.c, IPv4) functions.

The weakness was shared 04/22/2007 (Website). The advisory is available at debian.org. This vulnerability is handled as CVE-2007-2172 since 04/22/2007. Local access is required to approach this attack. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 25963 (Debian DSA-1363-1 : linux-2.6 - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155181 (Oracle Enterprise Linux Kernel Security and Bug Fix Update (ELSA-2007-1049)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 5 months after the disclosure of the vulnerability.
