- Qt SVG in Qt 5.0.0 through 5.15.2 and 6.0.0 through 6.2.1 has an out-of-bounds write in QtPrivate::QCommonArrayOps<QPainterPath::Element>::growAppend (called from QPainterPath::addPath and QPathClipper::intersect). (CVE-2021-45930)

- A flaw was found in Qt. An out-of-bounds read vulnerability was found in QRadialFetchSimd in qt/qtbase/src/gui/painting/qdrawhelper_p.h in Qt/Qtbase. While rendering and displaying a crafted Scalable Vector Graphics (SVG) file this flaw may lead to an unauthorized memory access. The highest threat from this vulnerability is to data confidentiality and the application availability. (CVE-2021-3481)
