> 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.
