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.

An update of the cryptsetup package has been released.

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2022:0370 advisory.

  - 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 Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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.

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-027 advisory.

The remote Ubuntu 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5286-1 advisory.

    Milan Broz discovered that cryptsetup incorrectly handled LUKS2 reencryption recovery. An attacker with     physical access to modify the encrypted device header may trigger the device to be unencrypted the next     time it is mounted by the user.

    On Ubuntu 20.04 LTS, this issue was fixed by disabling the online reencryption feature.
