The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple 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)
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.
