Linux Kernel 2.6.9/2.6.18 information disclosure

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 2.6.9/2.6.18 (Operating System) and classified as problematic. This vulnerability affects an unknown functionality. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. CVE summarizes:

Unspecified vulnerability in the 32-bit and 64-bit emulation in the Linux kernel 2.6.9, 2.6.18, and probably other versions allows local users to read uninitialized memory via unknown vectors involving a crafted binary.

The bug was discovered 06/25/2008. The weakness was presented 06/30/2008 by Tavis Ormandy as Bug 433938 as confirmed bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability was named CVE-2008-0598 since 02/05/2008. The exploitation appears to be easy. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

The vulnerability was handled as a non-public zero-day exploit for at least 645 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 67703 (Oracle Linux 4 : kernel (ELSA-2008-0508)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165701 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2008:048)).

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (43554), Tenable (67703), SecurityFocus (BID 29942†), OSVDB (48781†) and Secunia (SA30849†). See VDB-42990, VDB-42700, VDB-43656 and VDB-43584 for similar entries. Once again VulDB remains the best source for vulnerability data.
