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
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&gt; 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)

1. Download IBM JRE 7 from the following location: <http://www.ibm.com/support/fixcentral&gt; by keyword ‘Runtimes for Java Technology’. (The followings steps are using x86_64 as an example.)
2. Copy JRE package into the Analytics Server host and Analytics Node host(s).
3. On the Analytics Server host, stop pats, pars, and parb services
4. On the Analytics Server host, extract new JRE files and replace old JRE files in following directories

#{ANALYTICS_SERVER_TOP}\jre

#{ANALYTICS_SERVER_TOP}\report\jre

Where ANALYTICS_SERVER_TOP describes the top-level IBM Spectrum LSF Analytics server installation directory.

5. On the Analytics Server host, start pats, pars, and parb services on demand.
6. On the Analytics Node host, stop plc services
7. On the Analytics Node host, extract new JRE files and replace old JRE files in following directory

#{ANALYTICS_NODE_TOP}/jre/#{ARCH}/

Where ANALYTICS_NODE_TOP describes the top-level IBM Spectrum LSF Analytics node installation directory. ARCH describes the architecture of Analytics Node host. E.g. linux-x86_64

8. On the Analytics Node host, start plc service.
