Overview

org.graalvm.sdk:graal-sdk is a high-performance JDK distribution designed to accelerate the execution of applications written in Java and other JVM languages along with support for JavaScript, Ruby, Python, and a number of other popular languages.

Affected versions of this package are vulnerable to Access Restriction Bypass by an unauthenticated attacker with network access via multiple protocols. This is due to incorrect implementation of the ECDSA cryptographic signature in Java.

Notes:

  1. This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security.

  2. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service that supplies data to the APIs.
