EulerOS Virtualization 3.0.6.6 : cloud-init (EulerOS-SA-2022-2490)

high Nessus Plugin ID 165898

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

- The default cloud-init configuration, in cloud-init 0.6.2 and newer, included 'ssh_deletekeys: 0', disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances created by cloning a golden master or template system, sharing ssh host keys, and being able to impersonate one another or conduct man-in-the-middle attacks. (CVE-2018-10896)

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 cloud-init packages.
