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
Microsoft Publisher 2003 SP3 does not properly handle NULL values for unspecified data items, which allows remote attackers to execute arbitrary code via a crafted Publisher file, aka "Publisher Incorrect NULL Value Handling 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 · moderate confidence

Microsoft Publisher 2003 SP3 contains a memory corruption vulnerability in its file parsing logic where NULL values for unspecified data items are not properly handled. When parsing a specially crafted .pub file, the application dereferences an invalid pointer, allowing an attacker to achieve arbitrary code execution with the privileges of the user opening the file.

MitigationApply Microsoft security update KB2810047 to address the improper NULL value handling, and enforce policies prohibiting users from opening untrusted or unsolicited Publisher files from external sources.

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. Verify Microsoft Publisher 2003 is installed
    Open Programs and Features (appwiz.cpl) or check Add/Remove Programs, look for Microsoft Publisher 2003 in the installed software list
    Affected if Microsoft Publisher 2003 appears in the installed programs list
  2. Confirm the exact Publisher version
    Launch Publisher, go to Help menu, select About Microsoft Office Publisher, and note the version number displayed
    Affected if The version shown is Microsoft Publisher 2003 (exact version 11.x)
  3. Identify .pub file handling configuration
    Check if .pub file association is configured in Windows - right-click any .pub file, select Properties, verify it opens with Microsoft Publisher
    Affected if Windows associates .pub files with Microsoft Publisher 2003, meaning the vulnerable parsing code will execute when files are opened
  4. Determine if the system processes external .pub files
    Review whether users have the ability to open .pub files from external sources such as email attachments, downloads, or removable media
    Affected if Users can open .pub files from untrusted sources, which is required to trigger the vulnerability

The system is affected if Microsoft Publisher 2003 is installed and users can open specially crafted .pub files, as the vulnerability lies in the file parsing logic that handles NULL values in .pub files.

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

Apply Microsoft security update KB2810047 to address the improper NULL value handling, and enforce policies prohibiting users from opening untrusted or unsolicited Publisher files from external sources.

Recommended fix High confidence

Microsoft Office 2016 or newer (including Microsoft 365 subscription)

  1. 1. Verify the current Microsoft Publisher version by opening Publisher, clicking 'Help', and selecting 'About Microsoft Office Publisher'
  2. 2. Since Microsoft Publisher 2003 reached end of support on April 8, 2014 and no longer receives security updates, upgrade to a supported version
  3. 3. Obtain and install a supported Microsoft Office version (Office 2016 or newer, or Microsoft 365) that includes Publisher
  4. 4. After upgrading, verify the new Publisher version is running
  5. 5. Ensure Windows Update is enabled and configured to receive security updates for the new Office installation
  6. 6. Train users to avoid opening untrusted Publisher files from unknown sources as an additional precaution
Caveat Microsoft Publisher 2003 files (.pub) may need conversion when opened in newer versions; some legacy features or macros may not be supported in newer Office versions
