Linux Kernel 2.6.17.10/2.6.17.11/2.6.18 SCTP SO_LINGER resource management

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 2.6.17.10/2.6.17.11/2.6.18 (Operating System). It has been classified as problematic. This affects an unknown code block of the component SCTP. The manipulation of the argument SO_LINGER with an unknown input leads to a resource management vulnerability. CWE is classifying the issue as CWE-399. This is going to have an impact on availability. The summary by CVE is:

The Linux kernel 2.6.17.10 and 2.6.17.11 and 2.6.18-rc5 allows local users to cause a denial of service (crash) via an SCTP socket with a certain SO_LINGER value, possibly related to the patch for CVE-2006-3745. NOTE: older kernel versions for specific Linux distributions are also affected, due to backporting of the CVE-2006-3745 patch.

The bug was discovered 09/19/2006. The weakness was presented 09/19/2006 by Sridhar Samudrala (Website). The advisory is shared at debian.org. This vulnerability is uniquely identified as CVE-2006-4535 since 09/05/2006. Access to the local network is required for this attack. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 93 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 27927 (Ubuntu 5.04 / 5.10 / 6.06 LTS : linux-source-2.6.10/-2.6.12/-2.6.15 vulnerabilities (USN-347-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu 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)).
