Linux Kernel 2.6.10/2.6.11 Radeon Driver radeon_check_and_fixup_offset race condition

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 rated as problematic. This issue affects the function radeon_check_and_fixup_offset of the component Radeon Driver. The manipulation with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The reiserfs_copy_from_user_to_file_region function in reiserfs/file.c for Linux kernel 2.6.10 and 2.6.11 before 2.6.11-rc4, when running on 64-bit architectures, may allow local users to trigger a buffer overflow as a result of casting discrepancies between size_t and int data types.

The bug was discovered 02/24/2005. The weakness was presented 02/15/2005 by Eric Anholt with FreeBSD Team (Website). It is possible to read the advisory at kernel.org. The identification of this vulnerability is CVE-2005-0532 since 02/24/2005. Access to the local network is required for this attack. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

After immediately, there has been an exploit disclosed. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 53 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 18598 (Mandrake Linux Security Advisory : kernel (MDKSA-2005:110)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l.

Upgrading to version 2.6.11-RC4 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at kernel.org. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published 5 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (19329), Tenable (18598), SecurityFocus (BID 12555†), OSVDB (14871†) and Secunia (SA14270†). See VDB-1226, VDB-1227, VDB-1228 and VDB-1224 for similar entries. Be aware that VulDB is the high quality source for vulnerability data.
