Upgrade org.apache.spark:spark-core_2.11 to version 2.3.3 or higher.

Overview

org.apache.spark:spark-core_2.11 is a cluster computing system for Big Data.

Affected versions of this package are vulnerable to Information Exposure. In certain situations Spark would write user data to local disk unencrypted, even if spark.io.encryption.enabled=true. This includes cached blocks that are fetched to disk (controlled by spark.maxRemoteBlockSizeFetchToMem); in SparkR, using parallelize; in Pyspark, using broadcast and parallelize; and use of python udfs.
