CVE-2026-6040 A heap use-after-free existed when importing the blank-width characters of an ODF number format
Description
A heap use-after-free existed when importing the blank-width characters of an ODF number format. A position value read from the document was not checked against the length of the format-code string, so a malformed number format could be processed against memory outside that string. In fixed versions the position is bounds-checked before use.
