Linux Kernel 2.6.x ext2 File System denial of service

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, which was classified as problematic, was found in Linux Kernel 2.6.x (Operating System). This affects an unknown part of the component ext2 File System. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. The summary by CVE is:

The ext2 file system code in Linux kernel 2.6.x allows local users to cause a denial of service (crash) via an ext2 stream with malformed data structures that triggers an error in the ext2_check_page due to a length that is smaller than the minimum.

The bug was discovered 11/12/2006. The weakness was presented 11/21/2006 (Website). The advisory is shared at xforce.iss.net. This vulnerability is uniquely identified as CVE-2006-6054 since 11/21/2006. The exploitability is told to be difficult. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 9 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 25876 (RHEL 2.1 : kernel (RHSA-2007:0672)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Red Hat Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 156170 (Oracle Enterprise Linux Update for Kernel (ELSA-2007:0014)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 10 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (30201), Tenable (25876), SecurityFocus (BID 23104†), OSVDB (30295†) and Secunia (SA22837†). See VDB-2661, VDB-2828, VDB-33395 and VDB-33392 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
