Linux Kernel up to 2.6.16.16 and input validation

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.

Detailsinfo

A vulnerability was found in Linux Kernel up to 2.6.16.16 (Operating System). It has been classified as critical. Affected is an unknown code block. The manipulation of the argument and with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as 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. This is going to have an impact on availability. CVE summarizes:

SCTP in Linux kernel before 2.6.16.17 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a chunk length that is inconsistent with the actual length of provided parameters.

The bug was discovered 05/19/2006. The weakness was released 05/22/2006 by Mu Security with Mu Security research team (Website). The advisory is shared for download at us.debian.org. This vulnerability is traded as CVE-2006-1858 since 04/19/2006. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 3 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 22279 (CentOS 4 : kernel (CESA-2006:0617)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 156246 (Oracle Enterprise Linux Update for Kernel (ELSA-2006:0617, ELSA-2006:0689)).

Upgrading to version 2.6.16.17 eliminates this vulnerability. A possible mitigation has been published 4 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (26585), Tenable (22279), SecurityFocus (BID 18085†), OSVDB (25696†) and Secunia (SA20185†). Entries connected to this vulnerability are available at VDB-2256, VDB-2254, VDB-2255 and VDB-2257.
