Linux Kernel up to 2.6.7 privileges 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 has been found in Linux Kernel (Operating System) and classified as critical. This vulnerability affects an unknown function. The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Multiple unknown vulnerabilities in Linux kernel 2.4 and 2.6 allow local users to gain privileges or access kernel memory, as found by the Sparse source code checking tool.

The bug was discovered 06/18/2004. The weakness was disclosed 07/02/2004 by Roman Drahtmueller (LINUX) with SuSE (Website). The advisory is available at suse.de. This vulnerability was named CVE-2004-0495 since 05/27/2004. The attack needs to approached within the local network. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available. This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

A public exploit has been developed in ANSI C and been published 7 months after the advisory. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 5 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 13731 (Fedora Core 1 : kernel-2.4.22-1.2194.nptl (2004-186)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks and running in the context l.

Upgrading to version 2.4.27-rc3 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at securityfocus.com. The best possible mitigation is suggested to be patching the affected component. A possible mitigation has been published even before and not after the disclosure of the vulnerability.
