Linux Kernel 2.6.14.3/2.6.15 proc_misc.c 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.

A vulnerability was found in Linux Kernel 2.6.14.3/2.6.15 (Operating System). It has been classified as problematic. Affected is an unknown functionality of the file proc_misc.c. 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 confidentiality. CVE summarizes:

The procfs code (proc_misc.c) in Linux 2.6.14.3 and other versions before 2.6.15 allows attackers to read sensitive kernel memory via unspecified vectors in which a signed value is added to an unsigned value.

The bug was discovered 12/23/2005. The weakness was shared 12/31/2005 by Karl Janmar (Website). The advisory is shared for download at kernel.org. This vulnerability is traded as CVE-2005-4605 since 01/03/2006. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known.

A public exploit has been developed in ANSI C. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 65 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 21977 (CentOS 4 : kernel (CESA-2006:0101)), 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 117768 (CentOS Security Update for Kernel (CESA-2006:0101)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 3 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (23811), Tenable (21977) and Exploit-DB (9363). The entries 1712, 1942, 1945 and 1943 are related to this item.
