CVE-2022-25327: Google Fscrypt

Medium severity, CVSS 5.5. EPSS: 0.1% chance of exploitation in the next 30 days.

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

Affected products

• Google Fscrypt: before 0.3.3 (fixed in 0.3.3)
