CVE-2019-14904 - solaris_zone module accepts zone name and performs actions related to that.
However, there is no user input validation done while performing actions.
A malicious user could provide a crafted zone name which allows executing commands
into the server manipulating the module behaviour.
Adding user input validation as per Solaris Zone documentation fixes this issue.
