Fixed the following security issue:
- CVE-2020-0569: 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. This issue was verified on macOS and
Linux and probably affects all other Unix operating systems. This issue
does not affect Windows.
- CVE-2020-0570: 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.
This issue was verified on Linux and probably affects all Unix operating
systems, other than macOS (Darwin). This issue does not affect Windows.
