How to fix?

Upgrade openjdk-jre to version 16.0.1, 11.0.11, 8.0.291, 7.0.301 or higher.

Overview

openjdk-jre is a free and open-source implementation of the Java Platform, Standard Edition (Java SE).

Affected versions of this package are vulnerable to Cryptographic Weakness. A flaw was found in the way the Libraries component of OpenJDK enforced constraints defined in the jdk.jar.disabledAlgorithms security property. Verification of a JAR file signed using a disabled algorithm could succeed in certain cases, leading to bypass of the intended security restrictions.

This vulnerability applies to Java deployments that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security.
