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.
