Description
An issue was discovered in SDDM before 0.19.0. It incorrectly starts the X server in a way that – for a short time period – allows local unprivileged users to create a connection to the X server without providing proper authentication. A local attacker can thus access X server display contents and, for example, intercept keystrokes or access the clipboard. This is caused by a race condition during Xauthority file creation.
