There are multiple vulnerabilities in the IBM® SDK Java™ Technology Edition that is shipped with IBM WebSphere Application Server. These issues were disclosed as part of the IBM Java SDK updates in July 2018. These may affect some configurations of IBM WebSphere Application Server Traditional, IBM WebSphere Application Server Liberty and IBM WebSphere Application Server Hypervisor Edition.
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.
HP fixes are on a delayed schedule.
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.

NOTE: The July update added Endpoint identification enabled on LDAPS connections.
To improve the robustness of LDAPS (secure LDAP over TLS ) connections, endpoint identification algorithms have been enabled by default. There may be situations where some applications that were previously able to successfully connect to an LDAPS server may no longer be able to do so. Such applications may, if they deem appropriate, disable endpoint identification using a new system property: com.sun.jndi.ldap.object.disableEndpointIdentification.
Define this system property (or set it to true) to disable endpoint identification algorithms.
This javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException connecting to a LDAP server is not a Java Security issue. With this LDAP update, LDAP is asking JSSE to validate the LDAP server’s certificate to ensure it is compliant with hostname verification. With this change, if the server’s certificate is not compliant, then the exception will be thrown. In the past, LDAP did not request JSSE to perform hostname verification and a non-compliant server certificate would not have been caused an issue.
