"According to the versions of the systemd packages installed, the EulerOS Virtualization 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.");
