Upgrade org.graalvm.sdk:graal-sdk to version 20.3.4, 21.3.0 or higher.
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 Timing Attack. It was discovered that the TLS implementation in the JSSE component of OpenJDK used non-constant comparisons when checking various data (such as session identifiers or verification data blocks) during TLS handshakes. A malicious TLS client could possibly use this flaw to recover that data by observing timing differences in processing of various inputs.
