Description

This security bulletin contains information about 1 security vulnerability.


1) Improper Privilege Management (CVE-ID: CVE-2023-26604)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper privilege management 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.


Remediation

Install update from vendor's website.
