X.org X11 up to 7.1-1.1.0 DBE Extension ProcDbeSwapBuffers integer coercion

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 critical has been found in X.org X11 up to 7.1-1.1.0 (Windowing System Software). This affects the function ProcDbeSwapBuffers of the component DBE Extension. The manipulation with an unknown input leads to a integer coercion vulnerability. CWE is classifying the issue as CWE-192. Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Integer overflow in the ProcDbeSwapBuffers function in the DBE extension for X.Org 6.8.2, 6.9.0, 7.0, and 7.1, and XFree86 X server, allows local users to execute arbitrary code via a crafted X protocol request that triggers memory corruption during processing of unspecified data structures.

The bug was discovered 01/09/2007. The weakness was disclosed 01/10/2007 by Sean Larsson with iDefense (Website). The advisory is shared at labs.idefense.com. This vulnerability is uniquely identified as CVE-2006-6103 since 11/24/2006. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 24005 (CentOS 3 : XFree86 (CESA-2007:0002)), 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 156205 (Oracle Enterprise Linux Update for XFree86 (ELSA-2007:0002)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at x.org. A possible mitigation has been published 1 days after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (31379), Tenable (24005), SecurityFocus (BID 21968†), OSVDB (32086†) and Secunia (SA23670†). The entries VDB-2815, VDB-2816 and VDB-34129 are pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
