CVE-2020-0569

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)

Additional Changes:

For detailed information on changes in this release, see the Rocky Linux 8.3 Release Notes linked from the References section.

Out of bounds write in Intel(R) PROSet/Wireless WiFi products on Windows 10 may allow an authenticated user to potentially enable denial of service via local access.

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)

This update for libqt5-qtbase fixes the following issues:

Security issue fixed:

• CVE-2020-0569: Fixed a potential local code execution by loading plugins from CWD (bsc#1161167).

Other issue fixed:

• Fixed comboboxes not showing in correct location (bsc#1158667).

It was discovered that Qt incorrectly handled certain PPM images. If a user or automated system were tricked into opening a specially crafted PPM file, a remote attacker could cause Qt to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-19872)

It was discovered that Qt incorrectly handled certain text files. If a user or automated system were tricked into opening a specially crafted text file, a remote attacker could cause Qt to crash, resulting in a denial of service. This issue only affected Ubuntu 19.10. (CVE-2019-18281)

It was discovered that Qt incorrectly searched for plugins in the current working directory. An attacker could possibly use this issue to execute arbitrary code. (CVE-2020-0569)

It was discovered that Qt incorrectly searched for libraries relative to the current working directory. An attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 19.10. (CVE-2020-0570)
