Fix CVE-2020-14342: It was found that cifs-utils' mount.cifs was
invoking a shell when requesting the Samba password, which could be used
to inject arbitrary commands. An attacker able to invoke mount.cifs with
special permission, such as via sudo rules, could use this flaw to
escalate their privileges.
