How to fix?

Upgrade Ubuntu:24.04 libreoffice to version 4:24.2.7-0ubuntu0.24.04.7 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 WMF graphics, which may be embedded in documents. A heap buffer overflow existed when importing a text record that carries its own character advance widths. The count of advance values and the length of the text were read separately from the file and were not required to agree, so drawing the text walked the advance array by character position and ran past its end when the array was the shorter of the two. In fixed versions an advance array shorter than its text is ignored.
