发布于3月6日3月6日 Members CentOS Linux: CVE-2023-26604: Moderate: systemd security and bug fix update (CESA-2023:3837) Severity 7 CVSS (AV:L/AC:L/Au:S/C:C/I:C/A:C) Published 03/03/2023 Created 06/28/2023 Added 06/28/2023 Modified 01/28/2025 Description systemd before 247 does not adequately block local privilege escalation for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output.
