How to fix?

Upgrade Ubuntu:22.04 libreoffice to version 1:7.3.7-0ubuntu0.22.04.12 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libreoffice package and not the libreoffice package as distributed by Ubuntu. See How to fix? for Ubuntu:22.04 relevant fixed versions and status.

LibreOffice Calc can import tracked changes from a spreadsheet document. A heap buffer overflow existed when a document reused the same change identifier for two different kinds of change. The importer then treated one change object as a different, larger type and wrote past the end of its allocation. In fixed versions records with a duplicate identifier are rejected.
