CVE-2020-28049 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-11-21 3.3 LOW 6.3 MEDIUM
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.
CVE-2018-14345 1 Sddm Project 1 Sddm 2024-11-21 6.0 MEDIUM 7.5 HIGH
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.
CVE-2015-0856 2 Fedoraproject, Sddm Project 2 Fedora, Sddm 2024-11-21 4.6 MEDIUM N/A
daemon/Greeter.cpp in sddm before 0.13.0 does not properly disable the KDE crash handler, which allows local users to gain privileges by crashing a greeter when using certain themes, as demonstrated by the plasma-workspace breeze theme.
CVE-2014-7272 2 Fedoraproject, Sddm Project 2 Fedora, Sddm 2024-11-21 7.2 HIGH 7.8 HIGH
Simple Desktop Display Manager (SDDM) before 0.10.0 allows local users to gain root privileges because code running as root performs write operations within a user home directory, and this user may have created links in advance (exploitation requires the user to win a race condition in the ~/.Xauthority chown case, but not other cases).
CVE-2014-7271 2 Fedoraproject, Sddm Project 2 Fedora, Sddm 2024-11-21 4.6 MEDIUM 7.8 HIGH
Simple Desktop Display Manager (SDDM) before 0.10.0 allows local users to log in as user "sddm" without authentication.
