Apache Spark vulnerable to Improper Privilege Management

Details

As written in the advisory (Markdown source, shown as plain text).

In Apache Spark versions prior to versions 3.4.0 and 3.3.3, applications using spark-submit can specify a `proxy-user` to run as, limiting privileges. The application can execute code with the privileges of the submitting user, however, by providing malicious configuration-related classes on the classpath. This affects architectures relying on proxy-user, for example those using Apache Livy to manage submitted applications. Update to Apache Spark 3.4.0, 3.3.3, or later, and ensure that spark.submit.proxyUser.allowCustomClasspathInClusterMode is set to its default of "false", and is not overridden by submitted applications.
