A recent potential divide by zero in Qt SVG has been reported and has been assigned the CVE id CVE-2023-32573.
In QSvgFont, the m_unitsPerEm variable initialization is mishandled so if a SVG file that uses font-face without units-per-em set is passed to QSvgRenderer to render then it can trigger a division by zero.
Solution: Apply the following patch or update to Qt 5.15.14, Qt 6.2.9 or Qt 6.5.1
