I tested this in a VM with a freshly installed Ubuntu 20.04 Desktop. Following the steps in the description with released version 5.12.8+dfsg-0ubuntu1 freezes the entire VM.
After upgrading all the Qt packages to 5.12.8+dfsg-0ubuntu2 from proposed repo, the test program finishes immediately as expected. To upgrade, I used the following command line: sudo aptitude install -V qtbase5-dev/focal-proposed libqt5concurrent5/focal-proposed libqt5core5a/focal-proposed libqt5dbus5/focal-proposed libqt5gui5/focal-proposed qt5-qmake/focal- proposed qtbase5-dev-tools/focal-proposed qt5-qmake-bin/focal-proposed libqt5network5/focal-proposed libqt5printsupport5/focal-proposed libqt5sql5/focal-proposed libqt5test5/focal-proposed libqt5widgets5/focal-proposed libqt5xml5/focal-proposed ** Tags removed: verification-needed-focal ** Tags added: verification-done-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1950193 Title: libqt5svg5 affected by CVE-2021-38593 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/1950193/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
