An exploitable stack-based buffer overflow exists in the Microsoft Word document conversion functionality of the Antenna House Office Server Document Converter version V6.1 Pro MR2 for Linux64 (6,1,2018,0312). A crafted Microsoft Word (DOC) document can lead to a stack-based buffer overflow, resulting in remote code execution.

Security readout for executives and security teams

Plain-English summary

CVE-2018-3932 is a high-severity remote code execution risk in Antenna House Office Server Document Converter. A malicious Microsoft Word DOC file could crash or take over the conversion process if processed by the affected Linux64 version.

Executive priority

Treat as a priority remediation item where document conversion handles untrusted files. Business risk is strongest for upload portals, email processing, and automated conversion pipelines.

Technical view

The issue is a stack-based buffer overflow in Microsoft Word document conversion in Office Server Document Converter V6.1 Pro MR2 for Linux64 build 6,1,2018,0312. CVSS 3.0 is 8.8, network reachable, low complexity, no privileges, user interaction required, with high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is likely limited to organizations running the specific Antenna House converter build and accepting or processing DOC files from users, partners, email, portals, or automated workflows.

Exploitation context

The provided sources describe a crafted DOC causing stack-based overflow and possible remote code execution. They do not state active exploitation, and the CVE is not listed as KEV in the bundle.

Researcher notes

Evidence is narrow but clear: affected product/version, vulnerability class, attack vector, and impact are stated. The source bundle does not provide a named patch, mitigation, CWE, proof of active exploitation, or broader affected version range.

Mitigation direction

  • Inventory Antenna House Office Server Document Converter deployments and versions.
  • Check Antenna House guidance for fixed versions or vendor-recommended remediation.
  • Temporarily disable DOC conversion on affected systems if business impact allows.
  • Restrict document conversion inputs to trusted sources until remediation is confirmed.
  • Run conversion services with least privilege and isolation controls.

Validation and detection

  • Confirm whether Linux64 version V6.1 Pro MR2 build 6,1,2018,0312 is deployed.
  • Review file ingestion paths that can submit DOC files to the converter.
  • Check vendor release notes or support records for remediation status.
  • Verify vulnerable systems are not internet-facing document conversion endpoints.
  • Confirm monitoring covers crashes or abnormal behavior in conversion services.
