		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for systemd is now available for openEuler-20.03-LTS-SP1.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">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 &quot;systemctl status&quot; 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)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">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.</Note>
