CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 1CVE-2020-13962 – qt5: incorrectly calls SSL_shutdown() in OpenSSL mid-handshake causing denial of service in TLS applications
https://notcve.org/view.php?id=CVE-2020-13962
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.) Qt versiones 5.12.2 hasta 5.14.2, como es usado en compilaciones no oficiales de Mumble versión 1.3.0 y otros productos, maneja inapropiadamente la cola de errores de OpenSSL, lo que puede ser capaz de causar una denegación de servicio a usuarios de QSslSocket. Debido a que los errores se filtran en sesiones TLS no relacionadas, una sesión no relacionada puede ser desconectada cuando se comete un fallo en cualquier protocolo de enlace. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00004.html https://bugreports.qt.io/browse/QTBUG-83450 https://github.com/mumble-voip/mumble/issues/3679 https://github.com/mumble-voip/mumble/pull/4032 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4X6EDPIIAQPVP2CHL2CHDHJ25EECA7UE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UQJDBZUYMMF4R5QQKD2HTIKQU2NSKO63 https://lists.fedoraproject.org/archives/list/package-annou • CWE-391: Unchecked Error Condition •

CVSS: 8.6EPSS: 0%CPEs: 1EXPL: 1CVE-2018-21035 – qt5-qtwebsockets: websocket implementation allows only limited size for frames and messages therefore attacker can cause DOS
https://notcve.org/view.php?id=CVE-2018-21035
In Qt through 5.14.1, the WebSocket implementation accepts up to 2GB for frames and 2GB for messages. Smaller limits cannot be configured. This makes it easier for attackers to cause a denial of service (memory consumption). En Qt versiones hasta 5.14.1, la implementación de WebSocket acepta hasta 2GB para tramas y 2GB para mensajes. Los límites más pequeños no pueden ser configurados. • https://bugreports.qt.io/browse/QTBUG-70693 https://codereview.qt-project.org/c/qt/qtwebsockets/+/284735 https://access.redhat.com/security/cve/CVE-2018-21035 https://bugzilla.redhat.com/show_bug.cgi?id=1810964 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
