- Summary
- [none]
- Details
-
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.
