Subject [jira] [Created] (HADOOP-8461) Programatically prevent symlink attacks on hadoop pid files
Date Thu, 31 May 2012 21:30:23 GMT
Robert Joseph Evans created HADOOP-8461:

             Summary: Programatically prevent symlink attacks on hadoop pid files
                 Key: HADOOP-8461
                 URL: https://issues.apache.org/jira/browse/HADOOP-8461
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.0.0-alpha, 1.0.3
            Reporter: Robert Joseph Evans

pid files stored in  HADOOP_PID_DIR and HADOOP_SECURE_DN_PID_DIR are vulnerable to symlink
attacks when not properly set.  We should programatically prevent symlink attacks on these
files even if the directories are set to something that others can write to.
