These issues were disclosed as part of the IBM Java SDK updates in Oct. 2018. Vulnerability Details CVEID: CVE-2018-3180 DESCRIPTION: Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: JSSE). Supported versions that are affected are Java SE: 6u201, 7u191, 8u182 and 11; Java SE Embedded: 8u181; JRockit: R28.3.19. Difficult to exploit vulnerability allows unauthenticated attacker with network access via SSL/TLS to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded, JRockit accessible data as well as unauthorized read access to a subset of Java SE, Java SE Embedded, JRockit accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded, JRockit. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g. code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g. through a web service which supplies data to the APIs.

To solve the problem without updating the entire Recovery Expert product, the user can replace the existing JRE that is installed into the product installation tree in the "jre" directory with a newer JRE that includes the security fixes. Instructions to replace the IBM JRE for DB2 Recovery Expert for Linux, UNIX and Windows 1. Identify the version and platform of your DB2 Recovery Expert installation. 2. See the table below to find the IBM JRE download link that matches your product version and platform. If you cannot find a JRE download link for your product version and platform, contact IBM Technical Support and refer to this tech-note 3. Download the zip file (for example: ibm-java-jre-x.x-x.x-linux-x86_64.tgz) and extract it to a folder on a local file system (for example: /tmp/ ibm-jre-x.x-x.x). 4. Stop the DB2 Recovery Expert server using the stop.sh command (for example: /opt/ibm/RE/stop.sh). 5. Back-up and then delete the contents of the "jre" folder from your product installation directory (for example: /opt/ibm/RE/jre). 6. Copy the contents of the "jre" folder from the latest IBM JRE that you downloaded in Step 3 (for example: /tmp/ibm-jre-x.x-x.x/jre/) to the "jre" folder in your product installation directory (for example: /opt/ibm/RE/jre/).* 7. Ensure that the file permissions for the new JRE files and folders match the file permissions for the original JRE files and folders. If necessary, set 775 recursively. 8. Restart the DB2 Recovery Expert server using the start.sh command (for example: /opt/ibm/RE/start.sh). * NOTE: You must repeat from Step 6 again any time you install an APAR or upgrade to an affected version of DB2 Recovery Expert.
