CVE-2018-11804: Improper Input Validation

October 24, 2018 (updated December 11, 2018)

The Apache Spark Maven-based build includes a convenience script, build/mvn, that downloads and runs a zinc server to speed up compilation. It has been included in release branches since, up to and including master. This server will accept connections from external hosts by default. A specially-crafted request to the zinc server could cause it to reveal information in files readable to the developer account running the build.
