EulerOS 2.0 SP8 : cloud-init (EulerOS-SA-2021-2624)

medium Nessus Plugin ID 154795


The remote EulerOS host is missing a security update.


According to the versions of the cloud-init package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- When instructing cloud-init to set a random password for a new user account, versions before 21.2 would write that password to the world-readable log file /var/log/cloud-init-output.log. This could allow a local user to log in as another user. (CVE-2021-3429)

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.
