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 8.0 from the following location: http://www.ibm.com/support/fixcentral by keyword ‘Runtimes for Java Technology’. (The followings steps are using x86_64 as an example.)
2. Copy the tar package into the PM server host.
3. Log on the PM server host as root, stop jfd.

jadmin stop

4. On the PM server host, extract new JRE files and replace old folders with new ones.

chmod +x ibm-java-x86_64-jre-8.0-5.35.bin

./ibm-java-x86_64-jre-8.0-5.35.bin

mv /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre-old

mkdir -p /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre

cp -r ibm-java-x86_64-80/* /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre

mv /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre/jre/bin /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre

mv /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre/jre/lib /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre

mv /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre/jre/plugin /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre

rm -rf /opt/ppm/10.2/linux2.6-glibc2.3-x86_64/jre/jre

5. On the PM server host, start jfd
