Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Heap-based buffer overflow vulnerability in GDI+ library when parsing malformed PNG image files, allowing remote attackers to execute arbitrary code via crafted images. The vulnerability affects multiple Windows components and applications that use the GDI+ rendering library.

MitigationDeploy Microsoft security update MS09-062 (GDI+) to all affected systems. Where patching is not feasible, restrict untrusted PNG content from being processed by vulnerable applications and disable IE's GDI+ image handling for high-risk contexts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check GDI+ library version
    Locate gdiplus.dll on the system (typically in C:\Windows\System32 or C:\Windows\SysWOW64) and view its file properties to see the version number. Alternatively, run 'dir /a C:\Windows\System32\gdiplus.dll' to see version info.
    Affected if The file version is earlier than the patched version delivered by MS09-062 (the fixed version varies by Windows version but should be version 5.1.3102.5512 or higher for most systems).
  2. Verify MS09-062 security update installation
    Open Control Panel > Programs and Features > View installed updates, or run 'wmic qfe list' from command prompt, and search for update KB956572 or security update MS09-062.
    Affected if The MS09-062 update (KB956572) is NOT installed on the system.
  3. Check for vulnerable Internet Explorer 6
    Open Internet Explorer, go to Help > About Internet Explorer, or check Program Files for IE6 installation on the system.
    Affected if Internet Explorer version 6 is installed and in use.
  4. Detect vulnerable .NET Framework versions
    Check registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v1.1.4322 and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727 for installed versions, or use 'wmic product list' command.
    Affected if Microsoft .NET Framework versions 1.1 or 2.0 are installed without the MS09-062 update applied.
  5. Check for affected SQL Server 2005
    Check installed programs list or run 'SELECT @@VERSION' on SQL Server instances to identify SQL Server 2005 installations.
    Affected if Microsoft SQL Server 2005 is installed and has not been patched with MS09-062.

A system is affected if GDI+ (gdiplus.dll) lacks the MS09-062 update, or if any affected products (IE6, .NET 1.1/2.0, SQL Server 2005, Report Viewer 2005/2008) are present without the security patch applied.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Deploy Microsoft security update MS09-062 (GDI+) to all affected systems. Where patching is not feasible, restrict untrusted PNG content from being processed by vulnerable applications and disable IE's GDI+ image handling for high-risk contexts.

Recommended fix High confidence

Upgrade to Windows 10/11 (workstations) or Windows Server 2016/2019/2022 (servers), then apply latest cumulative security updates

  1. 1. Identify all systems running the affected Windows versions (Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008)
  2. 2. Schedule a maintenance window for the operating system upgrade
  3. 3. Back up all critical data and verify backup integrity
  4. 4. Upgrade to a supported Windows version (Windows 10 or Windows 11 for workstations, Windows Server 2016 or later for servers)
  5. 5. After upgrade, ensure all other affected software (.NET Framework, Internet Explorer, SQL Server, Report Viewer) are updated to supported versions
  6. 6. Verify that GDI+ and all graphics components are functioning correctly post-upgrade
  7. 7. Re-deploy security baseline configurations and endpoint protection
Caveat Older applications designed for Windows XP/2003/Vista may require compatibility testing or modernization; some legacy dependencies may not function on newer OS versions
