Hi, 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 Patches: dev: https://codereview.qt-project.org/c/qt/qtsvg/+/474093 Qt 6.5: https://codereview.qt-project.org/c/qt/qtsvg/+/474404 or https://download.qt.io/official_releases/qt/6.5/CVE-2023-32573-qtsvg-6.5.diff Qt 6.2: https://download.qt.io/official_releases/qt/6.2/CVE-2023-32573-qtsvg-6.2.diff Qt 5.15: https://download.qt.io/official_releases/qt/5.15/CVE-2023-32573-qtsvg-5.15.diff Kind regards, Andy -- Andy Shaw Director, Technical Customer Success The Qt Company _______________________________________________ Announce mailing list annou...@qt-project.org https://lists.qt-project.org/listinfo/announce -- Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
