CVE-2005-2124: Windows GDI32.DLL WMF Image Unchecked Buffer Code Execution

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: medium.

high priorityThe flaw allows remote code execution with complete confidentiality, integrity and availability impact, and EPSS is very high, though no KEV listing or confirmed public exploit is present in the record.

What it is

The Graphics Rendering Engine (GDI32.DLL) in Windows 2000 SP4, XP SP1/SP2 and Server 2003 SP1 contains an unchecked buffer when processing Windows Metafile (WMF) images, which can lead to a buffer overflow. A crafted WMF image can cause memory corruption that may be leveraged to run arbitrary code in the context of the affected process.

Impact

An attacker who successfully exploits the flaw can execute arbitrary code with the privileges of the user or service processing the image. This can lead to full system compromise depending on the process context.

Attack surface

The vulnerability is reached remotely over the network (AV:N) by supplying a crafted WMF image to a component that renders it, such as an application or service using GDI32.DLL. No authentication is required (Au:N), but the CVSS vector indicates high attack complexity (AC:H), and the description does not specify whether user interaction is needed.

Exploitation

The record is not listed in CISA KEV and no ransomware usage is documented, but EPSS is high (0.55713, 98.99th percentile), indicating a substantial predicted likelihood of exploitation activity. Reference tags include Patch and Vendor Advisory, but no public exploit tag is present.

What to do

• Apply the Microsoft security update for MS05-053 (or the latest cumulative update) to all affected Windows 2000 SP4, XP SP1/SP2 and Server 2003 SP1 systems.
• Upgrade or retire unsupported Windows versions that cannot receive current security fixes.
• Restrict or block untrusted WMF image files at email gateways, web proxies and file transfer points where feasible.
• Harden rendering paths by disabling or limiting unnecessary image rendering services and applications that process WMF files.
• Monitor vendor and CERT advisories for updated guidance and any revised patches.

Detection

• Monitor for crashes or abnormal process terminations in applications that render WMF images, especially GDI32.DLL-related faults.
• Inspect network and email traffic for WMF files arriving from untrusted external sources.
• Review endpoint logs for suspicious child processes spawned by image-rendering applications or services.
• Use file reputation and sandboxing to detonate suspicious WMF files before they reach production systems.
