CVE-2026-63276

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

Description A stack buffer overflow occurs during the conversion of CFF fonts to Type 1 fonts, a process that takes place when a document is exported to PDF and CFF fonts are embedded. The issue arises because converted operators are written into a fixed-size buffer without verifying if they fit, allowing a glyph that emits numerous operators to write beyond the buffer boundary.

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