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

- Ubuntu 18.04 LTS


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

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


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)

Please note that with this update, the OpenJDK package in Ubuntu 18.04 LTS has transitioned from OpenJDK 10 to OpenJDK 11. Several additional packages were updated to be compatible with OpenJDK 11.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04 LTS:
openjdk-11-jdk 11.0.2+9-3ubuntu1~18.04.3
openjdk-11-jre 11.0.2+9-3ubuntu1~18.04.3

This update uses a new upstream release, which includes additional bug fixes. After a standard system update you need to restart any Java applications or applets to make all the necessary changes.
