USN-3949-1: OpenJDK 11 vulnerability
16 April 2019

openjdk-lts vulnerability
A security issue affects these releases of Ubuntu and its derivatives:

  o Ubuntu 18.04 LTS

Summary

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

Software Description

  o openjdk-lts - 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)

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

To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .

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.
