How to fix?

There is no fixed version for killing.

Overview

killing is a Kill Process

Affected versions of this package are vulnerable to Arbitrary Command Injection. If attacker-controlled user input is given, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization.

PoC (provided by reporter): 

var killing = require('killing');

killing('$(touch success)')
.then(function() {})
.catch(function() {});

(A file called success will be created as a result of the execution of touch success.)
