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.

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)

Updated qtbase5 packages fix security vulnerabilities:

QPluginLoader in Qt versions 5.0.0 through 5.13.2 would search for certain plugins first on the current working directory of the application, which allows an attacker that can place files in the file system and influence the working directory of Qt-based applications to load and execute malicious code (CVE-2020-0569).

QLibrary in Qt versions 5.12.0 through 5.14.0, on certain x86 machines, would search for certain libraries and plugins relative to current working directory of the application, which allows an attacker that can place files in the file system and influence the working directory of Qt-based applications to load and execute malicious code (CVE-2020-0570).

Also, a file conflict that caused issues when upgrading from Mageia 6 has been fixed (mga#25418)

These are all security issues fixed in the libQt5Bootstrap-devel-static-32bit-5.15.2+kde222-1.3 package on the GA media of openSUSE Tumbleweed.
