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.

NVD · unedited
The Graphics Component in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 does not properly process JPEG images, which makes it easier for remote attackers to bypass the ASLR protection mechanism via a crafted web site, aka "Graphics Component Information Disclosure Vulnerability."

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

A vulnerability in the Windows Graphics Component allows improper processing of crafted JPEG images, enabling remote attackers to leak memory addresses and bypass ASLR protection. This information disclosure vulnerability requires user interaction (visiting a malicious website) to trigger the crafted image processing.

MitigationApply the relevant Microsoft security update (MS14-085 or subsequent cumulative updates) to all affected Windows systems. Since this is an information disclosure vulnerability enabling ASLR bypass, prioritize patching internet-facing systems and client workstations.

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. Identify Windows version
    Run 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to determine the installed Windows version
    Affected if The version matches Windows 7, 8, 8.1, Rt, Rt 8.1, Server 2003, Server 2008, Server 2008 R2, Server 2012, or Server 2012 R2
  2. Check for MS14-085 security update
    Run 'wmic qfe list' or check Windows Update history for security update KB2999226 (the MS14-085 patch)
    Affected if The security update KB2999226 is NOT installed on the system
  3. Verify graphics component exposure
    Confirm the system can process JPEG images through built-in Windows graphics components (default behavior for affected versions)
    Affected if The Windows Graphics Device Interface (GDI+) is in use, which processes JPEG images by default on affected systems
  4. Confirm user interaction vector
    Check if users can browse the internet or open image files (Internet Explorer, Edge, or other applications that process images)
    Affected if Users have the ability to view images from web browsers or image viewers on the affected system

The system is affected if it runs an unpatched Windows 7/8/8.1/Rt version or unpatched Windows Server 2003/2008/2012 variant and processes JPEG images through the Windows Graphics Component.
