Name of the Vulnerable Software and Affected Versions Java SE versions 11.0.3 and 12.0.1

Description The issue is related to the Java Secure Socket Extension (JSSE) component, which is vulnerable to errors when handling attached OCSP responses during TLS handshakes. This difficult-to-exploit vulnerability allows an unauthenticated attacker with network access via TLS to compromise Java SE, requiring human interaction from a person other than the attacker. Successful attacks can result in unauthorized access to critical data or complete access to all Java SE accessible data. This vulnerability applies to Java deployments that load and run untrusted code, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, and rely on the Java sandbox for security.

Recommendations For Java SE version 11.0.3, update to a version that includes the fix for this issue. For Java SE version 12.0.1, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the JSSE component until a patch is available. Avoid using the JSSE component for handling untrusted code until the issue is resolved.
