CVE-2020-28049 (GCVE-0-2020-28049)
Vulnerability from cvelistv5 – Published: 2020-11-04 00:00 – Updated: 2024-10-15 18:10
VLAI
Summary
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.
Severity
6.3 (Medium)

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).
Severity
No CVSS data available.
