Affected: AlmaLinux:8: qt5-qtbase-static, AlmaLinux:8: qt5-qttools-static

Qt is a software toolkit for developing applications. The qt5-base packages contain base tools for string, xml, and network handling in Qt.

Security Fix(es):

* qt: XML entity expansion vulnerability (CVE-2015-9541)

* qt5-qtwebsockets: websocket implementation allows only limited size for frames and messages therefore attacker can cause DOS (CVE-2018-21035)

* qt: files placed by attacker can influence the working directory and lead to malicious code execution (CVE-2020-0569)

* qt: files placed by attacker can influence the working directory and lead to malicious code execution (CVE-2020-0570)

* qt5: incorrectly calls SSL_shutdown() in OpenSSL mid-handshake causing denial of service in TLS applications (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.)
