qt5-qtwebengine can cause Chrome notification crash
published 4 days ago
Summary
The qt5-qtwebengine component used by Google Chrome versions before 90 may mishandle memory when showing notifications, which could lead to a crash or allow an attacker to run code. Updating Chrome to version 90 or later (and keeping the qt5-qtwebengine package current) removes the risk.
What to do
- Update cleanstart qt5-qtwebengine to version 5.15.3_git20210510-r1.
