CVE-2020-28049
https://notcve.org/view.php?id=CVE-2020-28049
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. Se detectó un problema en SDDM versiones anteriores a 0.19.0. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00031.html https://bugzilla.suse.com/show_bug.cgi?id=CVE-2020-28049 https://github.com/sddm/sddm/blob/v0.19.0/ChangeLog https://github.com/sddm/sddm/releases https://lists.debian.org/debian-lts-announce/2020/11/msg00009.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GT3EX5NSQJJAKY63ENSMEDX6NYZLYY3S https://security.gentoo.org/glsa/202402-02 https://www.debian.org/security/2020& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
