vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - qt: QPluginLoader loads plugins relative to CWD which could result in arbitrary code execution
    (CVE-2020-24742)

  - qt: incorrect integer overflow check (CVE-2023-51714)

  - Stack-based buffer overflow in QXmlSimpleReader in Qt 4.8.5 allows remote attackers to cause a denial of
    service (application crash) via a xml file with multiple nested open tags. (CVE-2016-10040)

  - An issue was discovered in Qt through 5.12.9, and 5.13.x through 5.15.x before 5.15.1. read_xbm_body in
    gui/image/qxbmhandler.cpp has a buffer over-read. (CVE-2020-17507)

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2020-0570. Reason: This candidate is a
    duplicate of CVE-2020-0570. A typo caused the wrong ID to be used. Notes: All CVE users should reference
    CVE-2020-0570 instead of this candidate. All references and descriptions in this candidate have been
    removed to prevent accidental usage (CVE-2020-24741)

  - 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)

  - Qt 5.x before 5.15.6 and 6.x through 6.1.2 has an out-of-bounds write in QOutlineMapper::convertPath
    (called from QRasterPaintEngine::fill and QPaintEngineEx::stroke). (CVE-2021-38593)

  - 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)

  - 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. (CVE-2023-32573)

  - An issue was discovered in Qt before 5.15.15, 6.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.2.
    Certificate validation for TLS does not always consider whether the root of a chain is a configured CA
    certificate. (CVE-2023-34410)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package
is installed.");
