systemd security update
An update for systemd is now available for openEuler-20.03-LTS-SP1.
systemd is a system and service manager that runs as PID 1 and starts the rest of the system.
Security Fix(es):
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.(CVE-2023-26604)
An update for systemd is now available for openEuler-20.03-LTS-SP1.
openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
