Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - It was found that a specially crafted LUKS header could trick cryptsetup into disabling encryption during the recovery of the device. An attacker with physical access to the medium, such as a flash disk, could use this flaw to force a user into permanently disabling the encryption layer of that medium.
 (CVE-2021-4122)

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.
