In Qt before 5.15.15, 6.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.2, there can be an application crash in QXmlStreamReader via a crafted XML string that triggers a situation in which a prefix is greater than a length.
CVE-2021-38593 2 Fedoraproject, Qt 2 Fedora, Qt 2024-02-03 5.0 MEDIUM 7.5 HIGH
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-2020-13962 4 Fedoraproject, Mumble, Opensuse and 1 more 4 Fedora, Mumble, Leap and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
Qt 5.12.2 through 5.14.2, as used in unofficial builds of Mumble 1.3.0 and other products, mishandles OpenSSL's error queue, which can cause a denial of service to QSslSocket users. Because errors leak in unrelated TLS sessions, an unrelated session may be disconnected when any handshake fails. (Mumble 1.3.1 is not affected, regardless of the Qt version.)
