"Description": "This update upgrades sddm to version 0.18.1-alt10. \nSecurity Fix(es):\n\n * BDU:2021-01700: Уязвимость компонента X server экранного менеджера SDDM, связанная с одновременным выполнением с использованием общего ресурса с неправильной синхронизацией, позволяющая нарушителю получить доступ к конфиденциальным данным и нарушить их целостность\n\n * 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.",
