The PAM module for fscrypt doesn’t adequately validate fscrypt metadata
files, allowing users to create malicious metadata files that prevent other
users from logging in. A local user can cause a denial of service by
creating a fscrypt metadata file that prevents other users from logging
into the system. We recommend upgrading to version 0.3.3 or above
