Description
LibreOffice can import PICT images, which may be embedded in documents. An out of bounds read existed when importing an image that uses a colour palette. The palette index held in the image data was used without being checked against the number of entries the palette has, so an index past the last entry read memory outside the palette. In fixed versions the palette index is limited to the entries present.
Affected products
- The Document Foundation LibreOffice: from 26.2 before < 26.2.5 — fixed in < 26.2.5
How to fix
Upgrade to a fixed version: The Document Foundation LibreOffice < 26.2.5. Check the vendor advisory for mitigations.
