These issues were disclosed as part of the IBM Java SDK updates in July 2018. Vulnerability Details If you run your own Java code using the IBM Java Runtime delivered with this product, you should evaluate your code to determine whether the complete list of vulnerabilities are applicable to your code. For a complete list of vulnerabilities please refer to the link for "IBM Java SDK Security Bulletin" located in the "References" section for more information. CVEID: CVE-2018-1656 DESCRIPTION: The IBM Java Runtime Environment''s Diagnostic Tooling Framework for Java (DTFJ) does not protect against path traversal attacks when extracting compressed dump files. CVSS Base Score: 7.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/144882 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N) CVEID: CVE-2018-12539 DESCRIPTION: Eclipse OpenJ9 could allow a local attacker to gain elevated privileges on the system, caused by the failure to restrict the use of Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations to only the process owner. An attacker could exploit this vulnerability to execute untrusted native code and gain elevated privileges on the system. CVSS Base Score: 8.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/148389 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) Affected Products and Versions IBM ILOG CPLEX Optimization Studio v12.8 and earlier Remediation/Fixes - From v12.4 to v12.5.1: IBM SDK, Java Technology Edition, Version 6 Service Refresh 16 Fix Pack 70 and subsequent releases - From v12.6 to v12.6.3: IBM SDK, Java Technology Edition, Version 7 Service Refresh 10 Fix Pack 30 and subsequent releases - From v12.7: IBM SDK, Java Technology Edition, Version 8 Service Refresh 5 Fix Pack 20 and subsequent releases The recommended solution is to download and install the appropriate version of IBM JRE as soon as practicable. o Before installing a newer version of IBM JRE, please ensure that you: o Close any open programs that you may have running; o Rename the initial directory of the IBM JRE (for example: with a .old at the end), o Download and install the appropriate IBM JRE version. Here are the detailed instructions for updating IBM JRE. You must verify that applying this fix does not cause any compatibility issues. For HP-UX, MacOS and Solaris, IBM recommends upgrading to a fixed, supported version/release/platform of the product.
