Summary

Uncontrolled Resource Consumption in github.com/google/fscrypt

Details

fscrypt through v0.3.2 creates a world-writable directory by default when setting up a filesystem, allowing unprivileged users to exhaust filesystem space. We recommend upgrading to fscrypt 0.3.3 or above and adjusting the permissions on existing fscrypt metadata directories where applicable.

Severity ?

5.5 (Medium)
