Linux Kernel 2.6.10/2.6.11 addr.c atm_get_addr memory corruption

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 2.6.10/2.6.11 (Operating System). It has been classified as problematic. This affects the function atm_get_addr of the file addr.c. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on integrity. The summary by CVE is:

The atm_get_addr function in addr.c for Linux kernel 2.6.10 and 2.6.11 before 2.6.11-rc4 may allow local users to trigger a buffer overflow via negative arguments.

The bug was discovered 02/15/2005. The weakness was published 05/02/2005 by Georgi Guninski (Website). It is possible to read the advisory at guninski.com. This vulnerability is uniquely identified as CVE-2005-0531 since 02/24/2005. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. 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 116 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 21928 (CentOS 3 / 4 : kernel (CESA-2005:366)), 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 117964 (CentOS Security Update for Kernel (CESA-2005:366)).
