These issues were disclosed as part of the IBM Java SDK updates in July 2018. An Open Source OpenSSL vulnerabilitiy has also been addressed. 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-2018-1656 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) CVEID: CVE-2018-0732 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the sending of a very large prime value to the client by a malicious server during key agreement in a TLS handshake. By spending an unreasonably long period of time generating a key for this prime, a remote attacker could exploit this vulnerability to cause the client to hang. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 144658 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) Affected Products and Versions * IBM Cognos TM1 10.2.2 Remediation/Fixes The recommended solution is to apply the fix for versions listed as soon as practical.
