Microsoft Windows 2000/Server 2003/XP MSDTC 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 has been found in Microsoft Windows 2000/Server 2003/XP (Operating System) and classified as critical. This vulnerability affects some unknown processing of the component MSDTC. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. CVE summarizes:

Heap-based buffer overflow in the CRpcIoManagerServer::BuildContext function in msdtcprx.dll for Microsoft Distributed Transaction Coordinator (MSDTC) for Windows NT 4.0 and Windows 2000 SP2 and SP3 allows remote attackers to execute arbitrary code via a long fifth argument to the BuildContextW or BuildContext opcode, which triggers a bug in the NdrAllocate function, aka the MSDTC Invalid Memory Access Vulnerability.

The bug was discovered 10/11/2005. The weakness was presented 05/09/2006 by Xiao Chen (McAfee) with eEye Digital Security und McAfee as MS06-018 as confirmed bulletin (Technet). The advisory is available at microsoft.com. This vulnerability was named CVE-2006-0034 since 11/30/2005. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2273 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 21334 (MS06-018: Vulnerability in Microsoft Distributed Transaction Coordinator Could Allow DoS (913580) (uncredentialed check)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 90310 (Microsoft Distributed Transaction Coordinator Could Allow Denial of Service (MS06-018)).

Applying the patch MS06-018 is able to eliminate this problem. The bugfix is ready for download at windowsupdate.microsoft.com. A possible mitigation has been published immediately after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 6455. In this case the pattern |05 00 00| is used for detection. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 3826.

The vulnerability is also documented in the databases at X-Force (25559), Tenable (21334), SecurityFocus (BID 17906†), OSVDB (25335†) and Secunia (SA20000†). See VDB-30131 for similar entry. If you want to get best quality of vulnerability data, you may have to visit VulDB.
