> 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.
