Guava is a suite of core and expanded libraries that include utility classes, google's collections, io classes, and much much more.

This project is a complete packaging of all the Guava libraries

by downloading the appropriate module and its dependencies.

Guava (complete) has only one code dependency - javax.annotation,
per the JSR-305 spec.</p>

Vulnerability Details

A temp directory creation vulnerability exist in Guava versions prior to 30.0 allowing an attacker with access to the machine to potentially access data in a temporary directory created by the Guava com.google.common.io.Files.createTempDir(). The permissions granted to the directory created default to the standard unix-like /tmp ones, leaving the files open. We recommend updating Guava to version 30.0 or later, or update to Java 7 or later, or to explicitly change the permissions after the creation of the directory if neither are possible.
