Recent Sddmproject Sddm Security Vulnerabilities

An issue was discovered in SDDM before 0.19.0

CVE-2020-28049 6.3 - Medium - November 04, 2020

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.

Race Condition

An issue was discovered in SDDM through 0.17.0

CVE-2018-14345 7.5 - High - July 17, 2018

An issue was discovered in SDDM through 0.17.0. If configured with ReuseSession=true, the password is not checked for users with an already existing session. Any user with access to the system D-Bus can therefore unlock any graphical session. This is related to daemon/Display.cpp and helper/backend/PamBackend.cpp.
