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
Buffer overflow in Microsoft Jet Database Engine 4.0 allows remote attackers to execute arbitrary code via a specially-crafted database query.

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 · moderate confidence

Buffer overflow vulnerability in Microsoft Jet Database Engine 4.0 allows remote attackers to execute arbitrary code through specially-crafted database queries. The flaw enables attackers to overwrite memory boundaries and inject malicious code.

MitigationApply Microsoft security patches for Jet Database Engine, keep Windows systems updated, and implement input validation on database query parameters.

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. Confirm Jet Database Engine is installed
    Search for msjet40.dll or msjetol40.dll in the Windows\System32 directory and other Jet-related DLLs. Use 'dir /s C:\msjet40.dll' or check file properties.
    Affected if The Jet DLL files (msjet40.dll, msjetol40.dll) exist on the system, indicating Jet 4.0 is present.
  2. Check the Jet database engine file version
    Right-click the msjet40.dll file in Windows\System32, select Properties, and view the Version tab to see the file version. Alternatively, use 'powershell (Get-Item C:\Windows\System32\msjet40.dll).VersionInfo'
    Affected if The file version is 4.0.x.x (where x is any sub-version), confirming Jet version 4.0 is installed.
  3. Identify applications using Jet database engine
    Check for Microsoft Access 2000/2002/2003, Visual Basic 6 applications, or other programs that rely on Jet databases. Check Add/Remove Programs or search for .mdb files created by Access/Jet.
    Affected if Applications that utilize Jet 4.0 databases are installed or used on the system.
  4. Verify database query handling is exposed
    Determine if the system accepts or processes database queries from untrusted sources. Check any web applications, file parsers, or services that open .mdb files or accept SQL-like input that gets processed by Jet.
    Affected if Applications or services can pass specially-crafted database queries to the Jet engine, enabling the buffer overflow to trigger.

If Microsoft Jet Database Engine version 4.0 is present and any application or service can feed it database queries, the system is affected by this vulnerability.
