Ubuntu Security Notice USN-3734-1
August 10, 2018

openjdk-8 vulnerability
==========================================================================

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

- Ubuntu 16.04 LTS

Summary:

Java applications could be made to use excessive memory.

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

Details:

It was discovered that the PatternSyntaxException class in OpenJDK
did not properly validate arguments passed to it. An attacker could
use this to possibly construct a class that caused a denial of service
(excessive memory consumption).

Update instructions:

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

Ubuntu 16.04 LTS:
openjdk-8-jdk 8u181-b13-0ubuntu0.16.04.1
openjdk-8-jre 8u181-b13-0ubuntu0.16.04.1
openjdk-8-jre-headless 8u181-b13-0ubuntu0.16.04.1
openjdk-8-jre-jamvm 8u181-b13-0ubuntu0.16.04.1

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.
