Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2022-01-01 04:45:08 UTC 
CVE-2021-45930 (https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=37025):

Qt SVG in Qt 5.0.0 through 6.2.1 has an out-of-bounds write in QtPrivate::QCommonArrayOps<QPainterPath::Element>::growAppend (called from QPainterPath::addPath and QPathClipper::intersect).
Comment 1 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2022-01-01 04:46:10 UTC 
We need https://github.com/qt/qtsvg/commit/a3b753c2d077313fc9eb93af547051b956e383fc which I don't see within Qt5PatchCollection (please verify though).
