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&gt; 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&gt; 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&gt; 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&gt; 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&gt; for more information

1. Download IBM JRE 7.0 x86_64 from the following location: <http://www.ibm.com/support/fixcentral&gt; by keyword ‘Runtimes for Java Technology’. (For POWER platform, download ppc64 version JRE tar package. 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. On management node, start GUI and PERF services

pcmadmin service start --group ALL

7. If high availability is enabled, start up standby management node, and replace bin, lib, plugin folders under /opt/pcm/web-portal/jre/linux-x86_64, on standby management node.
