        "Description": "This update upgrades timeshift to version 20.03-alt1. \nSecurity Fix(es):\n\n * BDU:2020-02872: Уязвимость функции init_tmp (TeeJee.FileSystem.vala) приложения восстановления системы Timeshift, позволяющая нарушителю выполнить произвольный код\n\n * CVE-2020-10174: init_tmp in TeeJee.FileSystem.vala in Timeshift before 20.03 unsafely reuses a preexisting temporary directory in the predictable location /tmp/timeshift. It follows symlinks in this location or uses directories owned by unprivileged users. Because Timeshift also executes scripts under this location, an attacker can attempt to win a race condition to replace scripts created by Timeshift with attacker-controlled scripts. Upon success, an attacker-controlled script is executed with full root privileges. This logic is practically always triggered when Timeshift runs regardless of the command-line arguments used.",
