Vulnerability Details

CVEID: CVE-2018-1890
DESCRIPTION: IBM SDK, Java Technology Edition Version 8 on the AIX platform
uses absolute RPATHs which may facilitate code injection and privilege
elevation by local users.
CVSS Base Score: 5.6
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152081 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L)

CVEID: CVE-2018-12547
DESCRIPTION: Eclipse OpenJ9 is vulnerable to a buffer overflow, caused by
improper bounds checking by the jio_snprintf() and jio_vsnprintf() functions.
By sending an overly long argument, a remote attacker could overflow a buffer
and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
157512 for the current score
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-2019-2426
DESCRIPTION: An unspecified vulnerability in Oracle Java SE related to the Java
SE Networking component could allow an unauthenticated attacker to obtain
sensitive information resulting in a low confidentiality impact using unknown
attack vectors.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
155744 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-2018-11212
DESCRIPTION: libjpeg is vulnerable to a denial of service, caused by
divide-by-zero error in the alloc_sarray function in jmemmgr.c. By persuading a
victim to open a specially-crafted file, a remote attacker could exploit this
vulnerability to cause the application to crash.
CVSS Base Score: 3.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
143429 for the current score
CVSS Environmental Score*: Undefined

Remediation/Fixes

 1. If your product is deployed on WebSphere Application Server (WAS) and your
    deployment does not use an Eclipse based client nor the RM Browser plugin,
    then it is sufficient to continue using the existing version of your IBM
    Rational product, and only upgrade the JRE in the WAS server.
 2. For the below remediations, if you have a WAS deployment, then WAS must
    also be remediated, in addition to performing your product upgrades. Follow
    instructions at Security Bulletin: Multiple Vulnerabilities in IBM(R) Java
    SDK affect WebSphere Application Server January 2019 CPU

    to get the WAS remediation.

 3. If you are deploying the Rational products to a WAS Liberty or a Tomcat
    Server, you will need to follow the instructions below to upgrade the JRE,
    and then must also configure to complete the upgrade process:

  o Stop the server: Navigate to the Server directory in your Ratonal product
    installation path and run this script: server.shutdown
  o Navigate to the server directory in your Rational product installation
    path, open server.startup script using prefered text editor (e.g., Notepad
    for Windows or Vim Editor for Linux) and add one more option to the
    healthcenter parameter set:
      - Search parameter -Dcom.ibm.java.diagnostics.healthcenter.agent in
        server.startup script to find the line containing the health center
        parameter.
        NOTE: For some Rational Collaborative Lifecycle Management versions,
        -Dcom.ibm.java.diagnostics.healthcenter.agent parameter may not be
        found in the server.startup, in this case the update is not needed and
        you can start using your server.
        Windows:
        Comment out the line (where HEALTHCENTER_OPTS parameter located) by
        inserting "rem " at the beginning of the line:
        Before modification:
        set HEALTHCENTER_OPTS=-agentlib:healthcenter ...
        After modification:
        rem set HEALTHCENTER_OPTS=-agentlib:healthcenter ...
        Linux:
        Comment out the line (where HEALTHCENTER_OPTS parameter located) by
        inserting "# " at the beginning of the line:
        Before modification:
        export HEALTHCENTER_OPTS="-agentlib:healthcenter ...
        After modification:
        # export HEALTHCENTER_OPTS="-agentlib:healthcenter ...
  o Start the server. Navigate to the Server directory in your Rational product
    installation path and run this script: server.startup.


STEPS TO APPLY THE REMEDIATION:

1. Optionally, upgrade your products to an Extended Maintenance Release
version: 5.0.2 or 6.0.2. Or optionally, upgrade to the latest 6.0.x version.

2. Optionally, apply the latest ifix for your installed version.

3. Obtain the latest Java JRE CPU update for the IBM Java SDK using the
following information.

  o For the 6.0.6 release: JRE 7.1.4.40(<product>-JavaSE-JRE-7.1SR4FP40) or JRE
    8.0.5.30(<product>-JavaSE-JRE-8.0SR5FP30)
      - Rational Collaborative Lifecycle Management 6.0.6
  o For the 6.0.2 release: JRE 7.1.4.40(<product>-JavaSE-JRE-7.1SR4FP40)
      - Rational Collaborative Lifecycle Management 6.0.2
  o For the 5.x releases:
      - IBM SDK Java(TM) Technology Edition, Version 6 is no longer supported on
        distributed platforms. IBM Collaborative Lifecycle Management (CLM)
        products version 5.x use Java 6 and are affected. IBM highly recommends
        customers to upgrade to Extended Maintenance Release 6.0.2 or 6.0.6 for
        those wishing the stability and support of an EMR release, or to the
        latest 6.0.x version for those desiring the latest features. For
        additional details review: Impact to CLM 5.x suite of products due to
        Java 6 EOS

4. Upgrade your JRE following the instructions in the link below:
How to update the IBM SDK for Java of IBM Rational products based on version
3.0.1.6 or later of IBM's Jazz technology

5. Navigate to the server directory in your Rational product installation path,
and go to jre/lib/security path.

6. Optionallly, If you have not performed a Licenses upgrade as described in
the link below, please follow the instructions to complete the setup:

No IBM Rational trial, server, or client access licenses available after
upgrading Java and/or listed products


Workarounds and Mitigations

None

Important Note

IBM strongly suggests that all System z customers be subscribed to the System z
Security Portal to receive the latest critical System z security and integrity
service. If you are not subscribed, see the instructions on the System z
Security web site. Security and integrity APARs and associated fixes will be
posted to this portal. IBM suggests reviewing the CVSS scores and applying all
security or integrity fixes as soon as possible to minimize any potential risk.
