Security Bulletin Document information More support for: IBM Spectrum Cluster Foundation Software version: All Versions Operating system(s): Platform Independent Reference #: 0883546 Modified date: 17 May 2019 Summary There are multiple vulnerabilities in IBM(R)Runtime Environment Java(TM)Version 7 used by IBM Platform Cluster Manager Standard Edition, IBM Platform Cluster Manager Advanced Edition, Platform HPC, and Spectrum Cluster Foundation. These issues have been addressed in IBM Java SDK updates in April 2019. Vulnerability Details CVEID: CVE-2019-2699 DESCRIPTION: Oracle's JREs/JDKs on Windows ship with an old version of a Microsoft DLL which contains a vulnerability. CVSS Base Score: 9 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 159791 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L) CVEID: CVE-2019-2698 DESCRIPTION: An attacker can use a maliciously crafted font to exploit a flaw in the JDK's font parsing code to overwrite memory addresses and cause a crash. Untrusted code running under a security manager may be able to elevate its privileges and execute arbitrary code. CVSS Base Score: 8.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 159790 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2019-2697 DESCRIPTION: An attacker can use a maliciously crafted font to exploit a flaw in the JDK's font parsing code to overwrite memory addresses and cause a crash. Untrusted code running under a security manager may be able to elevate its privileges and execute arbitrary code. CVSS Base Score: 8.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 159789 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L) CVEID: CVE-2019-2602 DESCRIPTION: A flaw in the java.math.BigDecimal API causes hangs when parsing certain String values. This potentially allows an attacker to inflict a denial-of-service. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 159698 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N) CVEID: CVE-2019-2684 DESCRIPTION: The Java runtime's java.rmi.Registry implementation does not check access privileges correctly for some remote calls. This allows an attacker to effectively replace a number of predefined static skeleton classes with dynamic malicious skeletons. CVSS Base Score: 5.9 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 159776 for more information 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) CVEID: CVE-2019-10245 DESCRIPTION: A flaw in the OpenJ9 class verifier potentially allows untrusted code to elevate its privileges and execute arbitrary code. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 160010 for more information 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 Platform Cluster Manager Version 4.2.0, 4.2.0.1, 4.2.0.2 and 4.2.1 Platform HPC Version 4.2.0 and 4.2.1 Spectrum Cluster Foundation 4.2.2 Remediation/Fixes <Product VRMF APAR Remediation/First Fix Platform Cluster 4.2.0, Manager 4.2.0.1, Standard 4.2.0.2, Edition 4.2.1 None See fix below Platform Cluster 4.2.0, Manager 4.2.0.1, Advanced 4.2.0.2, Edition 4.2.1 None See fix below 4.2.0, Platform HPC 4.2.1 None See fix below Spectrum Cluster Foundation 4.2.2 None See fix below Platform Cluster Manager 4.2.x & Platform HPC 4.2.x & Spectrum Cluster Foundation 4.2.2 1.

The followings steps are using x86_64 as an example.) 2. Copy the tar package into the management node. If high availability is enabled, copy the JRE tar package to standby management node, as well. 3. If high availability is enabled, shutdown standby management node to avoid triggering high availability. 4. On the management node, stop GUI and PERF services # pcmadmin service stop --group ALL 5. On management node, extract new JRE files and replace some old folders with new ones. # chmod +x ibm-java-x86_64-jre-7.0-10.45.bin # ./ibm-java-x86_64-jre-7.0-10.45.bin # mv /opt/pcm/jre/bin /opt/pcm/jre/bin-old # mv /opt/pcm/jre/lib /opt/pcm/jre/lib-old # mv /opt/pcm/jre/plugin /opt/pcm/jre/plugin-old # cp -r ibm-java-x86_64-70/jre/bin /opt/pcm/jre/ # cp -r ibm-java-x86_64-70/jre/lib /opt/pcm/jre/ # cp -r ibm-java-x86_64-70/jre/plugin /opt/pcm/jre/ # mv /opt/pcm/web-portal/jre/linux-x86_64/bin /opt/pcm/web-portal/jre/ linux-x86_64/bin-old # mv /opt/pcm/web-portal/jre/linux-x86_64/lib /opt/pcm/web-portal/jre/ linux-x86_64/lib-old # mv /opt/pcm/web-portal/jre/linux-x86_64/plugin /opt/pcm/web-portal/jre/ linux-x86_64/plugin-old # cp -r ibm-java-x86_64-70/jre/bin /opt/pcm/web-portal/jre/linux-x86_64/ # cp -r ibm-java-x86_64-70/jre/lib /opt/pcm/web-portal/jre/linux-x86_64/ # cp -r ibm-java-x86_64-70/jre/plugin /opt/pcm/web-portal/jre/linux-x86_64/ 6.
