Mageia 7: 2020-0080 Critical: Qtbase5 Malicious Code Threat

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)
