CVE-2026-63275

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

Description An issue exists when reading CFF (Compact Font Format) fonts that may be embedded in documents. A stack buffer overflow occurs during the processing of glyph hints because the number of hints is validated against an incorrect bound. This allows a glyph that declares more hints than the allocated array can hold to write data past the end of the buffer.

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