Linux Kernel up to 2.5 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 classified as problematic was found in Linux Kernel up to 2.5 (Operating System). Affected by this vulnerability is an unknown function. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect integrity, and availability. The summary by CVE is:

Buffer overflow in sysctl in the Linux Kernel 2.6 before 2.6.15 allows local users to corrupt user memory and possibly cause a denial of service via a long string, which causes sysctl to write a zero byte outside the buffer. NOTE: since the sysctl is called from a userland program that provides the argument, this might not be a vulnerability, unless a legitimate user-assisted or setuid scenario can be identified.

The weakness was disclosed 12/31/2005 by Yi Yang (Website). The advisory is shared at debian.org. This vulnerability is known as CVE-2005-4618 since 01/05/2006. The exploitation appears to be easy. An attack has to be approached locally. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 22559 (Debian DSA-1017-1 : kernel-source-2.6.8 - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks.

Upgrading to version 2.6 eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (23989), Tenable (22559), SecurityFocus (BID 16141†), Secunia (SA18216†) and Vulnerability Center (SBV-16370†). The entries VDB-1942, VDB-1945, VDB-1943 and VDB-1944 are pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
