Linux Kernel 2.6.26.5 crafted input validation

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.

Summaryinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel 2.6.26.5. The affected element is the function crafted. Performing a manipulation results in input validation. This vulnerability is known as CVE-2008-4410. No exploit is available. It is advisable to upgrade the affected component.

Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel 2.6.26.5 (Operating System). This affects the function crafted. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

The vmi_write_ldt_entry function in arch/x86/kernel/vmi_32.c in the Virtual Machine Interface (VMI) in the Linux kernel 2.6.26.5 invokes write_idt_entry where write_ldt_entry was intended, which allows local users to cause a denial of service (persistent application failure) via crafted function calls, related to the Java Runtime Environment (JRE) experiencing improper LDT selector state, a different vulnerability than CVE-2008-3247.

The bug was discovered 10/03/2008. The weakness was published 10/03/2008 by Zachary Amsden (Website). The advisory is shared at redhat.com. This vulnerability is uniquely identified as CVE-2008-4410 since 10/03/2008. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 82 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 34480 (Fedora 9 : kernel-2.6.26.6-79.fc9 (2008-8929)), 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. The commercial vulnerability scanner Qualys is able to test this issue with plugin 116022 (SUSE Security Announcement: Linux Kernel (SUSE-SA:2008:053)).

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 (45687), Tenable (34480), SecurityFocus (BID 31565†), OSVDB (48743†) and Secunia (SA32124†). Similar entries are available at VDB-44544, VDB-44542 and VDB-43869. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
