Overview
Affected versions of this package are vulnerable to Incorrect Default Permissions. Beginning in v1.4.1 and prior to v1.4.9, due to an incomplete fix for CVE-2021-24031, the Zstandard command-line utility created output files with default permissions and restricted those permissions immediately afterwards. Output files could therefore momentarily be readable or writable to unintended parties.
Remediation
Upgrade libzstd
to version or higher.
