x/vulndb: potential Go vuln in github.com/etcd-io/etcd: CVE-2020-15113

[tatianab]

CVE-2020-15113 references github.com/etcd-io/etcd, which may be a Go module.

Description:
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).
