Uncontrolled recursion in the SVG parser and renderer of the Qt SVG module (QtSvg) in Qt Group Qt allows attackers to cause a denial of service (application crash via stack exhaustion) via a crafted SVG file with deeply nested elements.
A type confusion vulnerability in Qt SVG allows an attacker to cause an application crash via a crafted SVG image. When processing SVG marker references, the renderer retrieves a node by its id attribute and casts it to QSvgMarker* without verifying the node type. A non-marker element (such as a <line> element) that references itself as a marker triggers an out-of-bounds heap read due to the object size difference between QSvgLine and QSvgMarker, followed by an endless recursion that bypasses the marker recursion guard through incorrect virtual dispatch. The result is an application crash (denial of service). This issue affects Qt SV
The module will parse a <pattern> node which is not a child of a structural node. The node will be deleted after creation but might be accessed later leading to a use after free.
Integer Overflow vulnerability in qsvghandler.cpp in Qt qtsvg versions 5.15.1, 6.0.0, 6.0.2, and 6.2, allows local attackers to cause a denial of service (DoS).
In Qt before 5.15.14, 6.0.x through 6.2.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.1, QtSvg QSvgFont m_unitsPerEm initialization is mishandled.
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.
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).
An issue was discovered in Qt before 5.11.3. A malformed SVG image causes a segmentation fault in qsvghandler.cpp.
