Incorrect Default Permissions

Affecting libzstd package, versions <1.3.3+dfsg-2ubuntu1.2

Overview

Affected versions of this package are vulnerable to Incorrect Default Permissions. In the Zstandard command-line utility prior to v1.4.1, output files were created with default permissions. Correct file permissions (matching the input) would only be set at completion time. Output files could therefore be readable or writable to unintended parties.

Remediation

Upgrade libzstd to version or higher.
