qt5-qtbase-5.12.5-6.el8, qt5-qttools-5.12.5-2.el8, qt5-qtwebsockets-5.12.5-2.el8

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)

CVE-2015-9541
Qt through 5.14 allows an exponential XML entity expansion attack via a crafted SVG document that is mishandled in QXmlStreamReader, a related issue to CVE-2003-1564.
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).
CVE-2020-0569
** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.
CVE-2020-0570
Uncontrolled search path in the QT Library before 5.14.0, 5.12.7 and 5.9.10 may allow an authenticated user to potentially enable elevation of privilege via local access.
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.)
