LibreOffice before 4.3.5 allows remote attackers to cause a denial of service (invalid write operation and crash) and possibly execute arbitrary code via a crafted RTF file.

Analyst readout for executives and security teams

Plain-English summary

A malicious RTF document can crash LibreOffice versions before 4.3.5 and may allow code execution. The main business concern is legacy desktops or servers that open outside documents with old LibreOffice builds. The sources do not show known active exploitation.

Executive priority

Address during legacy software cleanup, with higher priority for teams handling external documents. The issue is old, but outdated office suites remain attractive because document opening is a common user workflow and possible code execution is cited.

Technical view

CVE-2014-9093 describes an invalid write operation in LibreOffice before 4.3.5 when processing crafted RTF files. Public records state denial of service and possible arbitrary code execution, but provide no CVSS, CWE, or detailed affected component data in the supplied bundle.

Likely exposure

Exposure is most likely where LibreOffice before 4.3.5 remains installed and users open RTF files from email, downloads, shared drives, or external parties. Modern managed environments are less likely exposed unless legacy images, embedded workflows, or unsupported Linux distributions remain in use.

Exploitation context

The attack path requires a crafted RTF file being processed by vulnerable LibreOffice. The supplied sources do not cite exploitation in the wild, and CISA KEV status is false. Treat exploitation claims beyond crash and possible code execution as unproven from this bundle.

Researcher notes

Evidence is limited to public CVE text, mailing-list references, bug tracker confirmation, and distribution advisories. The bundle does not provide root-cause detail, exploit maturity, fixed commit, CVSS, or affected subcomponent. Avoid overstating exploitability beyond possible arbitrary code execution.

Mitigation direction

  • Upgrade LibreOffice to 4.3.5 or later, or a vendor package containing the fix.
  • Prioritize endpoints and workflows that open external RTF documents.
  • Quarantine or restrict untrusted RTF attachments until vulnerable systems are remediated.
  • Retire unsupported LibreOffice builds and legacy OS images.
  • Check vendor advisories for distribution-specific fixed package versions.

Validation and detection

  • Inventory LibreOffice versions and flag any installation before 4.3.5.
  • Compare Linux package versions against relevant Fedora, Debian, Ubuntu, or Gentoo advisories.
  • Review email and web controls for RTF attachment handling.
  • Check endpoint telemetry for legacy LibreOffice launches against external documents.
  • Do not validate by opening suspicious crafted files on production systems.
