CVE-2026-8356

Name of the Vulnerable Software and Affected Versions LibreOffice (affected versions not specified)

Description A stack buffer overflow occurs when importing presentations in the legacy binary PPT format. The issue arises during the import of a colour-replacement record where two fixed-size colour tables are filled from the file. Because the write position is not reset between the two passes over the record, a file with combined colour counts exceeding the table size writes past the end of the tables on the stack.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
