Detailed paths

• Introduced through: org.keycloak:keycloak-quarkus-server-deployment@999.0.0-SNAPSHOT › org.keycloak:keycloak-quarkus-server@999.0.0-SNAPSHOT › com.google.guava:guava@30.1-jre

Overview

com.google.guava:guava is a set of core libraries that includes new collection types (such as multimap and multiset,immutable collections, a graph library, functional types, an in-memory cache and more.

Affected versions of this package are vulnerable to Creation of Temporary File in Directory with Insecure Permissions due to the use of Java's default temporary directory for file creation in FileBackedOutputStream. Other users and apps on the machine with access to the default Java temporary directory can access the files created by this class. This more fully addresses the underlying issue described in CVE-2020-8908, by deprecating the permissive temp file creation behavior.

NOTE: Even though the security vulnerability is fixed in version 32.0.0, the maintainers recommend using version 32.0.1, as version 32.0.0 breaks some functionality under Windows.

Remediation

Upgrade com.google.guava:guava to version 32.0.0-android, 32.0.0-jre or higher.
