             Summary: Docker container launch use popen have risk of shell expansion
                 Key: YARN-8207
                 URL: https://issues.apache.org/jira/browse/YARN-8207
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: yarn-native-services
            Reporter: Eric Yang


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.
