How to fix?

Upgrade go.etcd.io/etcd/v3/pkg/fileutil to version 3.4.10 or higher.

Overview

Affected versions of this package are vulnerable to Insecure Permissions. Certain directory paths are created (etcd data directory and the directory path when provided to automatically generate self-signed certificates for TLS connections with clients) with restricted access permissions (700) by using the os.MkdirAll. This function does not perform any permission checks when a given directory path exists already. A possible workaround is to ensure the directories have the desired permission (700).
