2021-03-05漏洞描述
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.解决建议
建议您更新当前系统或软件至最新版，完成漏洞的修复。
