How to fix?

Upgrade Ubuntu:24.04 libreoffice to version 4:24.2.7-0ubuntu0.24.04.6 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:24.04 relevant fixed versions and status.

LibreOffice can import drawings in the DXF format used by CAD software. A heap buffer overflow existed when importing a DXF polyline. The point count taken from the file was truncated to a 16-bit value when the point buffer was sized, while the full count was used to fill it, so a polyline whose point count exceeded the 16-bit range was written past the end of the buffer. In fixed versions such oversized polylines are rejected.
