Improper Preservation of Permissions

In etcd before versions 3.3.23 and 3.4.10, 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).

All versions before 3.3.23, all versions starting from 3.4.0-rc.0 before 3.4.10

Upgrade to versions 3.3.23, 3.4.10 or above.
