|---|---|---|---|
| Maven | org.apache.hadoop:hadoop-yarn-server | < 2.10.2 | 2.10.2 |
| Maven | org.apache.hadoop:hadoop-yarn-server | >= 3.0.0, < 3.2.4 | 3.2.4 |

Details
As written in the advisory (Markdown source, shown as plain text).
ZKConfigurationStore which is optionally used by CapacityScheduler of Apache Hadoop YARN deserializes data obtained from ZooKeeper without validation. An attacker having access to ZooKeeper can run arbitrary commands as YARN user by exploiting this. Users should upgrade to Apache Hadoop 2.10.2, 3.2.4, 3.3.4 or later (containing YARN-11126) if ZKConfigurationStore is used.
