Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10 - Ubuntu 16.04 LTS

Summary:

Java applets or applications could be made to expose sensitive information.

Software Description: - openjdk-lts: Open Source Java implementation - openjdk-8: Open Source Java implementation

Details:

It was discovered that a memory disclosure issue existed in the OpenJDK Library subsystem. An attacker could use this to expose sensitive information and possibly bypass Java sandbox restrictions. (CVE-2019-2422)

Update instructions:
