Linux Kernel 2.6.23 in 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 classified as critical was found in Linux Kernel 2.6.23 (Operating System). Affected by this vulnerability is the function in. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. The summary by CVE is:

The Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.27 does not properly handle a protocol violation in which a parameter has an invalid length, which allows attackers to cause a denial of service (panic) via unspecified vectors, related to sctp_sf_violation_paramlen, sctp_sf_abort_violation, sctp_make_abort_violation, and incorrect data types in function calls.

The bug was discovered 09/30/2008. The weakness was disclosed 10/20/2008 by David S. Miller (Website). It is possible to read the advisory at ubuntu.com. This vulnerability is known as CVE-2008-4618 since 10/20/2008. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 377 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 35036 (Debian DSA-1681-1 : linux-2.6.24 - denial of service/privilege escalation), 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 116074 (Debian Update for linux-2.6.24).

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (46034), Tenable (35036), SecurityFocus (BID 31848†), OSVDB (50077†) and Secunia (SA32918†). The entries VDB-45132, VDB-45085, VDB-45061 and VDB-44965 are pretty similar. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
