USN-3875-1: OpenJDK vulnerability

30 January 2019

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




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
Ubuntu 16.04

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.
