Linux Kernel up to 2.5 ip_nat_proto_tcp.c 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, which was classified as critical, has been found in Linux Kernel up to 2.5 (Operating System). This issue affects an unknown functionality of the file ip_nat_proto_tcp.c. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is availability. The summary by CVE is:

The NAT code (1) ip_nat_proto_tcp.c and (2) ip_nat_proto_udp.c in Linux kernel 2.6 before 2.6.13 and 2.4 before 2.4.32-rc1 incorrectly declares a variable to be static, which allows remote attackers to cause a denial of service (memory corruption) by causing two packets for the same protocol to be NATed at the same time, which leads to memory corruption.

The bug was discovered 11/22/2005. The weakness was published 10/20/2005 (Website). It is possible to read the advisory at securityfocus.com. The identification of this vulnerability is CVE-2005-3275 since 10/20/2005. The exploitation is known to be difficult. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 21943 (CentOS 4 : kernel (CESA-2005:514)), 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 117811 (CentOS Security Update for Kernel (CESA-2005:514)).

Upgrading to version 2.6 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.
