Description

Spark's Apache 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 1.3.x, 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. Note that this issue does not affect end users of Spark, only developers building Spark from source code.

Affected products

• Apache Software Foundation Apache Spark: from 1.3.0 before 2.2.3; from 2.3.0 before 2.3.3 — fixed in 2.2.3, 2.3.3

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Spark 2.2.3, 2.3.3. Check the vendor advisory for mitigations.
