Ubuntu Security Notice USN-3830-1

openjdk-8, openjdk-lts regression

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS


USN-3804-1 introduced a regression in OpenJDK.

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


USN-3804-1 fixed vulnerabilities in OpenJDK. Unfortunately, that update
introduced a regression when validating JAR files that prevented Java
applications from finding classes in some situations. This update
fixes the problem.

We apologize for the inconvenience.

Update instructions:

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

Ubuntu 18.04 LTS:
  openjdk-11-jdk                  10.0.2+13-1ubuntu0.18.04.4
  openjdk-11-jre                  10.0.2+13-1ubuntu0.18.04.4
  openjdk-11-jre-headless         10.0.2+13-1ubuntu0.18.04.4

Ubuntu 16.04 LTS:
  openjdk-8-jdk                   8u191-b12-0ubuntu0.16.04.1
  openjdk-8-jre                   8u191-b12-0ubuntu0.16.04.1
  openjdk-8-jre-headless          8u191-b12-0ubuntu0.16.04.1
  openjdk-8-jre-jamvm             8u191-b12-0ubuntu0.16.04.1

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.
