> Container-executor code utilize a string buffer to construct docker run 
> command, and pass the string buffer to popen for execution.  Popen spawn a 
> shell to run the command.  Some arguments for docker run are still vulnerable 
> to shell expansion.  The possible solution is to convert from char * buffer 
> to string array for execv to avoid shell expansion.
