IBM Decision Optimization Center 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) Affected Products and Versions IBM Decision Optimization Center 3.9 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 IBM Java SDK as soon as practicable.
