Microsoft Windows 2000/Server 2003/XP VML Vector Markup Language 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.

A vulnerability, which was classified as critical, was found in Microsoft Windows 2000/Server 2003/XP (Operating System). This affects an unknown code of the component VML Vector Markup Language Handler. 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 Vector Markup Language (VML) implementation (vgx.dll) in Microsoft Internet Explorer 5.01, 6, and 7 on Windows 2000 SP4, XP SP2, Server 2003, and Server 2003 SP1 allows remote attackers to execute arbitrary code via a crafted web page that contains unspecified integer properties that cause insufficient memory allocation and trigger a buffer overflow, aka the "VML Buffer Overrun Vulnerability."

The bug was discovered 10/03/2006. The weakness was released 01/09/2007 by Jospeh Moti with iDEFENSE (Website). It is possible to read the advisory at labs.idefense.com.
