IBM CPLEX Optimization Studio and IBM CPLEX Enterprise Server have addressed the applicable CVEs. 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 additional Java vulnerabilities are applicable to your code. For a complete list of vulnerabilities, refer to the "IBM Java SDK Security Bulletin", located in the References section for more information. CVEID: CVE-2018-1890 DESCRIPTION: IBM SDK, Java Technology Edition Version 8 on the AIX platform uses absolute RPATHs which may facilitate code injection and privilege elevation by local users. CVSS Base Score: 5.6 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 152081 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L) CVEID: CVE-2018-12547 DESCRIPTION: Eclipse OpenJ9 is vulnerable to a buffer overflow, caused by improper bounds checking by the jio_snprintf() and jio_vsnprintf() functions. By sending an overly long argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash. CVSS Base Score: 9.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 157512 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2019-2426 DESCRIPTION: An unspecified vulnerability in Oracle Java SE related to the Java SE Networking component could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 155744 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) Affected Products and Versions IBM CPLEX Optimization Studio and IBM CPLEX Enterprise Server 12.9 and earlier releases IBM SDK, Java Technology Edition, Version 7 Service Refresh 10 Fix Pack 35 and earlier releases IBM SDK, Java Technology Edition, Version 8 Service Refresh 5 Fix Pack 27 and earlier releases Remediation/Fixes The recommended solution is to download and install the appropriate version of IBM JRE as soon as practicable. Please note that Java 6 is no longer supported anymore. IBM recommends upgrading to COS 12.9 and subsequent releases. 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. IBM ILOG CPLEX Optimization Studio and IBM ILOG CPLEX Enterprise Server - From v12.6 to v12.6.3: IBM JRE Version 7 Service Refresh 10 Fix Pack 40 and subsequent releases - From v12.7: IBM JRE Version 8 Service Refresh 5 Fix Pack 30 and subsequent releases You must verify that applying this fix does not cause any compatibility issues. Here are the detailed instructions for updating IBM JRE. For HP-UX, MacOS and Solaris, IBM recommends upgrading to a fixed, supported version/release/platform of the product.
