发布于3月6日3月6日 Members Oracle Linux: CVE-2023-26604: ELSA-2024-7705:systemd security update (MODERATE) (Multiple Advisories) Severity 6 CVSS (AV:L/AC:L/Au:S/C:C/I:N/A:C) Published 03/03/2023 Created 07/25/2023 Added 07/21/2023 Modified 12/06/2024 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. A vulnerability was found in the systemd package. The systemd package does not adequately block local privilege escalation for some Sudo configurations, for example, 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 issue 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.
