WP1StylesListener.cpp, WP5StylesListener.cpp, and WP42StylesListener.cpp in libwpd 0.10.1 mishandle iterators, which allows remote attackers to cause a denial of service (heap-based buffer over-read in the WPXTableList class in WPXTable.cpp). This vulnerability can be triggered in LibreOffice before 5.3.7. It may lead to suffering a remote attack against a LibreOffice application.

Security readout for executives and security teams

Plain-English summary

CVE-2017-14226 is a document-parsing flaw in libwpd that can crash LibreOffice when it processes a malicious WordPerfect-related document. The public record describes denial of service from a heap-based buffer over-read, not confirmed code execution. Risk is highest where users or automated systems open untrusted office documents.

Executive priority

Treat as a targeted availability risk, not an emergency, unless the organization processes untrusted documents at scale. Prioritize patching exposed document workflows and user endpoints that receive external office files.

Technical view

libwpd 0.10.1 mishandles iterators in WP1StylesListener.cpp, WP5StylesListener.cpp, and WP42StylesListener.cpp, causing a heap-based buffer over-read in WPXTableList within WPXTable.cpp. The CVE states this can be triggered in LibreOffice before 5.3.7 via document handling and can remotely affect a LibreOffice application.

Likely exposure

Exposure is likely limited to systems using vulnerable libwpd or LibreOffice before 5.3.7, especially desktops, mail gateways, preview services, or document-processing pipelines that handle untrusted WordPerfect files.

Exploitation context

The source bundle does not show CISA KEV listing, active exploitation, exploit availability, or weaponized details. The described attack vector is remote delivery of a crafted document that causes application denial of service during parsing.

Researcher notes

Evidence supports denial of service from iterator mishandling and heap over-read in libwpd, with LibreOffice before 5.3.7 noted as triggerable. No CVSS, CWE, affected CPEs, exploit status, or detailed fixed release mapping is provided in the bundle.

Mitigation direction

  • Upgrade LibreOffice before 5.3.7 to a maintained fixed release.
  • Apply vendor or distro packages containing the referenced libwpd fixes.
  • Restrict automatic preview or conversion of untrusted WordPerfect documents.
  • Check current vendor guidance where fixed package versions are unclear.

Validation and detection

  • Inventory LibreOffice versions and flag installs older than 5.3.7.
  • Identify bundled or system libwpd 0.10.1 deployments.
  • Confirm packages include vendor backports or the referenced libwpd commits.
  • Review document-processing services for exposure to untrusted uploads or email attachments.
