CVE-2021-45930 – qt: out-of-bounds write may lead to DoS

https://notcve.org/view.php?id=CVE-2021-45930

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). Qt SVG en Qt versiones 5.0.0 hasta 6.2.1, presenta una escritura fuera de límites en la función QtPrivate::QCommonArrayOps(QPainterPath::Element)::growAppend (llamada desde QPainterPath::addPath y QPathClipper::intersect). A flaw was found in qtsvg's qsvghandler.cpp module. An attacker who is able to submit a crafted image file to an application that uses qsvghandler could cause an out-of-bounds write and potential denial of service to occur, depending on the application. • https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=37025 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=37306 https://github.com/google/oss-fuzz-vulns/blob/main/vulns/qt/OSV-2021-1121.yaml https://github.com/qt/qtsvg/commit/36cfd9efb9b22b891adee9c48d30202289cfa620 https://github.com/qt/qtsvg/commit/79bb9f51fa374106a612d17c9d98d35d807be670 https://github.com/qt/qtsvg/commit/a3b753c2d077313fc9eb93af547051b956e383fc https://lists.debian.org/debian-lts-announce/2022/01/msg00020.html https://lists&# • CWE-787: Out-of-bounds Write •
