CVE-2024-12425

Arbitrary .ttf file write via embedded font paths

Published Jan 7, 2025 · Updated Nov 3, 2025

Path traversal in LibreOffice 24.8 before 24.8.4 allows attackers to write embedded font data to writable locations via a crafted document. The embedded-font extractor trusts path names stored in supported document formats instead of confining extracted fonts to temporary files, while appending .ttf to the chosen path. Exploitation requires the document to be opened, and writes remain limited to locations writable with the LibreOffice user's permissions and filenames ending in .ttf.
