How to fix?

Upgrade Alpine:3.11 zstd to version 1.4.9-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream zstd package and not the zstd package as distributed by Alpine. See How to fix? for Alpine:3.11 relevant fixed versions and status.

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.
