Heap buffer overflow when replaying deferred OOXML parser events for a text box element, fixed upstream in LibreOffice 25.8.7 and 26.2.3. Debian trixie ships LibreOffice 25.2.3, which does not contain the vulnerable code: the Debian security team marks trixie (and bookworm) as not-affected ("Vulnerable code not present"). No Echo patch is required. Re-evaluate if this spec is ever rebased to a newer LibreOffice release that predates the upstream fix. https://security-tracker.debian.org/tracker/CVE-2026-6047
