Steve Beattie
==========================================================================
Ubuntu Security Notice USN-3875-1
January 30, 2019

openjdk-8, openjdk-lts vulnerability
==========================================================================

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:

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

Ubuntu 18.10:
  openjdk-11-jdk                  11.0.1+13-3ubuntu3.18.10.1
  openjdk-11-jre                  11.0.1+13-3ubuntu3.18.10.1
  openjdk-11-jre-headless         11.0.1+13-3ubuntu3.18.10.1

Ubuntu 16.04 LTS:
  openjdk-8-jdk                   8u191-b12-2ubuntu0.16.04.1
  openjdk-8-jre                   8u191-b12-2ubuntu0.16.04.1
  openjdk-8-jre-headless          8u191-b12-2ubuntu0.16.04.1
  openjdk-8-jre-jamvm             8u191-b12-2ubuntu0.16.04.1

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.
