Security Bulletin
Summary
An unspecified vulnerability has been identified in IBM Java Runtime that could affect DataQuant for z/OS.
Vulnerability Details
DESCRIPTION:
A widely used function in the OpenJ9 JVM is vulnerable to buffer overlows. Multiple Java Runtime components use the vulnerable code, so the issue can manifest in a number of different ways.
The fix ensures that the buffer cannot overflow.
CVEID: CVE-2018-1890
CVSS Base Score: 5.6
DESCRIPTION:
On the AIX platform, the IBM Java 8 executable contains inappropriate absolute RPATHs, which may allow local users to inject code into JVM processes launched by other users with higher privileges.
The fix removes the unsafe RPATHs.
CVEID: CVE-2018-12549
CVSS Base Score: 9.8
DESCRIPTION:
A flaw in the OpenJ9 JIT compiler allows unprivileged code to access to access sensitive methods in the internal class sun.misc.Unsafe, which allows the untrusted code to elevate its privileges.
The fix prevents optimized unprivileged code from accessing sun.misc.Unsafe.
CVEID: CVE-2019-2426
CVSS Base Score: 3.7
DESCRIPTION:
The transparent NTLM authentication implementation in java.net.HttpURLConnection exposes the user's NTLM credentials to any server that requests them.
The fix disables transparent NTLM authentication by default. A new system property (jdk.http.ntlm.transparentAuth) allows the user to enable transparent NTLM authentication for all hosts or trusted hosts only.
CVEID: CVE-2018-11212
CVSS Base Score: 5.3
DESCRIPTION:
A flaw in the Java runtime's JPEG parser allows maliciously crafted JPEG data to inflict a denial-of-service by triggering a JVM crash.
The fix ensures that the bad JPEG data is handled gracefully.

Remediation/Fixes
Steps to update Java for IBM DataQuant:
1. Close DataQuant.
2. Download JRE 8.0.5.30 version from IBM Java download portal.
3. Replace jre folder at the install directory location > C:\Program Files (x86)\IBM\IBM DataQuant\DataQuant for Workstation. Replace with contents in step # 2.
4. Download eclipse oxygen from https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/oxygen/3a/eclipse-jee-oxygen-3a-win32-x86_64.zip
5. Extract the eclipse oxygen and copy the plugin - org.apache.jasper.glassfish_2.2.2.v201501141630.jar from eclipse-jee-oxygen-3a-win32-x86_64\eclipse\plugins
6. Copy org.apache.jasper.glassfish_2.2.2.v201501141630.jar in the folder where DataQuant is installed - C:\Program Files (x86)\IBM\IBM DataQuant\DataQuant for Workstation\plugins
7. Delete the older plugin org.apache.jasper.glassfish_2.2.2.v201205150955.jar from the DataQuant install directory
