Background
github.com/google/fscrypt is a Go package that provides a set of tools for managing Linux filesystem encryption. It allows users to encrypt and decrypt files and directories using the Linux kernel's filesystem-level encryption feature. This package is widely used in various applications and systems that require file encryption. However, versions up to 0.3.2 of fscrypt suffer from a vulnerability that can lead to uncontrolled resource consumption.
Vulnerability Detail
The vulnerability in fscrypt versions up to 0.3.2 arises from the creation of a world-writable directory by default when setting up a filesystem. This directory can be exploited by unprivileged users to exhaust the filesystem space, potentially causing denial-of-service conditions. The issue can be mitigated by upgrading to fscrypt version 0.3.3 or above and adjusting the permissions on existing fscrypt metadata directories where applicable.
