Microsoft Windows 2000/XP WMF/EMF File 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 has been found in Microsoft Windows 2000/XP (Operating System) and classified as very critical. This vulnerability affects an unknown function of the component WMF/EMF File Handler. The manipulation with an unknown input leads to a integer coercion vulnerability. The CWE definition for the vulnerability is CWE-192. Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Multiple integer overflows in the Graphics Rendering Engine (GDI32.DLL) in Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1 allow remote attackers to execute arbitrary code via crafted Windows Metafile (WMF) and Enhanced Metafile (EMF) format images that lead to heap-based buffer overflows, as demonstrated using MRBP16::bCheckRecord.

The bug was discovered 11/08/2005. The weakness was released 11/08/2005 by Peter Ferrie (DiGiT) with eEye Digital Security as MS05-053 as confirmed bulletin (Technet).
