-------------------------------
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.
