6, 7 and 8 used by IBM ILOG CPLEX Optimization Studio. These issues were
disclosed as part of the IBM Java SDK updates in July 2018.
If you run your own Java code using the IBM Java Runtime delivered with this

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.
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)
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.
