CVE-2026-63272
NVD: LibreOffice can import WMF graphics, which may be embedded in documents. NVD: A heap buffer overflow existed when importing a text record that carries its own character advance widths. NVD: 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.
