Security Bulletin: Vulnerability in IBM Java SDK affects Rational Lifecycle
Integration Adapter for HP ALM (CVE-2015-7575)
Security Bulletin
Document information
More support for:
Rational Lifecycle Integration Adapters
General Information
Software version:
1.1.2, 1.1.2.1, 1.1.2.2, 1.1.2.3, 1.1.2.4, 1.1.2.5, 1.1.3, 1.1.3.1, 1.1.3.2
Operating system(s):
Linux, Windows
Software edition:
Standard
Reference #:
1976185
Modified date:
2016-08-24
Summary
There is a vulnerability in IBM SDK Java Technology Edition, Version 6.0.16.2
that is used by Rational Lifecycle Integration Adapter for HP ALM. This
vulnerability, commonly referred to as SLOTH, was disclosed as part of the
IBM Java SDK updates in January 2016.
Vulnerability Details
CVEID:
CVE-2015-7575
DESCRIPTION:
The TLS protocol could allow weaker than expected security caused by a
collision attack when using the MD5 hash function for signing a
ServerKeyExchange message during a TLS handshake. An attacker could exploit
this vulnerability using man-in-the-middle techniques to impersonate a TLS
server and obtain credentials. This vulnerability is commonly referred to as
SLOTH.
CVSS Base Score: 7.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/109415
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N)
Affected Products and Versions
IBM Rational Lifecycle Integration Adapter for HP ALM 1.1.2 and later
versions
Remediation/Fixes
The fix is available on
Fix Central
You should verify applying this fix does not cause any compatibility issues.
The fix disables MD5 signature hash by default. If you change the default
setting after applying the fix, you will expose yourself to the attack
described above. IBM recommends that you review your entire environment to
identify other areas where you have enabled the MD5 signature hash and take
appropriate mitigation and remediation actions.
To update IBM Rational Lifecycle Integration Adapter with a corrected JRE,
follow the instructions below. Depending on how you deployed the products,
and depending on your usage scenarios, you might need to upgrade the IBM SDK,
Java Technology Edition in IBM WebSphere Application Server and Apache
Tomcat. Be sure to upgrade all the components that you use in your deployment
uses.
NOTE: IBM SDK, Java Technology Edition is only included in IBM Rational
Lifecycle Integration Adapter version 1.1.2 or later. Previous versions of
the Rational Lifecycle Integration Adapter Standard Edition HP Adapter were
released as WAR files only. Please consult with the application server
documentation for updating the IBM SDK, Java Technology Edition.
Upgrading the JRE for a
WebSphere Application Server
installation
If your products are deployed on WebSphere Application Server,
Java SDK Upgrade Policy for the IBM WebSphere Application Server
lists IBM SDK, Java Technology Edition upgrades that are available. Also
check the
Product Security Incident Response Blog
for any recent security bulletins for WebSphere Application Server that may
have fixpacks or interim fixes for the JRE.
Upgrading the
IBM SDK, Java Technology Edition
for a Tomcat installations
1. Stop the Rational Lifecycle Integration Adapter server.
Note
: The applications may be running in different application server instances
or using a delegated converter.
2. Go to the original installation directory, and rename the /jre folder
<InstallDir>/server/jre
to
<InstallDir>/server/jre-Original
This ensures that the original JRE is kept as a backup in the event a restore
is required.
Example (Linux):
mv <OrigInstallDir>/server/jre <OrigInstallDir>/server/jre-Original
3. Extract the new JRE archive provided by support to the Installation
directory.
Example (Linux):
unzip <newInsallZip> -d <InstallDir>/server/
4. Remove the Apache Tomcat temporary files in the following directories:
<OrigInstallDir>/server/tomcat/temp
<OrigInstallDir>/server/tomcat/work/Catalina/localhost
5. Restart the Rational Lifecycle Integration Adapter server
Workarounds and Mitigations
For CVE-2015-7575:
Users of Java 7 and later can address the issue by updating the
/jre/lib/security/java.security file as follows (
both steps are required
):
Add MD5 to the jdk.certpath.disabledAlgorithms property - e.g.
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024,
MD5
Add MD5withRSA to the jdk.tls.disabledAlgorithms property - e.g.
jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768,
MD5withRSA
Java 6 requires code changes in the JSSE component in addition to the
java.security file modifications, so upgrading the JDK is the only solution.
