Overview

Affected versions of this package are vulnerable to Out-of-bounds Write due to failing to properly validate the font width and height when rendering certain unicode sequences. A malicious actor may craft a font capable of triggering this issue, allowing modifications in unauthorized memory segments, causing data integrity problems or leading to denial of service.
