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 Office Word 2000 SP3, 2002 SP3, 2003 SP3, and 2007 Gold and SP1; Outlook 2007 Gold and SP1; Word Viewer 2003 Gold and SP3; Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats Gold and SP1; Office 2004 and 2008 for Mac; and Open XML File Format Converter for Mac allow remote attackers to execute arbitrary code via crafted control words related to multiple Drawing Object tags in (1) an RTF file or (2) a rich text e-mail message, which triggers incorrect memory allocation and a heap-based buffer overflow, aka "Word RTF Object Parsing Vulnerability," a different vulnerability than CVE-2008-4030.

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

This is a heap-based buffer overflow vulnerability in Microsoft Office's RTF parser triggered by crafted Drawing Object tags in RTF files or rich text e-mail messages. The vulnerability causes incorrect memory allocation during parsing, leading to arbitrary code execution with the privileges of the user opening the malicious file.

MitigationApply Microsoft security patches for the affected Office versions. Until patches are applied, users should avoid opening untrusted RTF files or disable RTF preview in Outlook.

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 installed Microsoft Office Word version
    Open Word, go to Help > About Microsoft Office Word, or check Add/Remove Programs for the installed version. For Outlook, check Help > About Microsoft Office Outlook.

  2. Identify installed Microsoft Office Compatibility Pack version
    Check Add/Remove Programs or Programs and Features for Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint File Formats.
    Affected if Compatibility Pack is installed (any version)
  3. Check for Microsoft Office Word Viewer 2003
    Check Add/Remove Programs for Microsoft Office Word Viewer 2003.
    Affected if Word Viewer 2003 is installed
  4. Check for Microsoft Works 8.0
    Check Add/Remove Programs for Microsoft Works version 8.0.
    Affected if Microsoft Works 8.0 is installed
  5. Check for Microsoft Open Xml File Format Converter
    Check Add/Remove Programs for Microsoft Open Xml File Format Converter.
    Affected if Open Xml File Format Converter is installed (any version)

Mitigation

Apply Microsoft security patches for the affected Office versions. Until patches are applied, users should avoid opening untrusted RTF files or disable RTF preview in Outlook.

Recommended fix High confidence

Apply Microsoft Security Bulletin MS08-072 security updates, then update to the latest available service packs for each affected product (e.g., Office Word 2007 to SP2, Office 2004/2008 for Mac to latest versions)

  1. Locate and apply the security update from Microsoft Security Bulletin MS08-072, which addresses this specific vulnerability (Word RTF Object Parsing Vulnerability)
  2. For Microsoft Office Word 2000 SP3 and Word 2002 SP3: Apply the security update specific to your version from MS08-072
  3. For Microsoft Office Word 2003 SP3: Apply the MS08-072 security update
  4. For Microsoft Office Word 2007 (Gold or SP1): Apply MS08-072 security update, then install the latest service pack (SP2)
  5. For Microsoft Office Outlook 2007 (Gold or SP1): Apply MS08-072 security update, then install the latest service pack (SP2)
  6. For Office Compatibility Pack for Word, Excel, PowerPoint 2007: Apply the MS08-072 security update for the compatibility pack
  7. For Office 2004 for Mac: Apply the security update for Office 2004 for Mac from the MS08-072 bulletin
  8. For Office 2008 for Mac: Apply the security update for Office 2008 for Mac from MS08-072
Caveat The security updates are routine patches with no expected breaking changes; however, test in a non-production environment before broad deployment to ensure compatibility with existing documents and workflows
