EulerOS 2.0 SP10 : systemd (EulerOS-SA-2023-1814)

high Nessus Plugin ID 175316

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the systemd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected systemd packages.
