Vulnerability Details
IBM Jazz Team Server and the CLM applications (RRC, RTC, RQM, RDNG), RELM,
Rhapsody DM, and RSA DM applications are affected by the following
vulnerabilities disclosed in and corrected by the IBM Java SDK updates in
January 2016 and October 2015:

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.

Remediation/Fixes
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 the your
Rational product, and only upgrade the JRE in the WAS server according to
these instructions:
Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect WebSphere
Application Server January 2016 CPU
The January 2016 update contains all of the corrections from the October 2015
update. The October update is listed here for convenience, but upgrade to the
January 2016 update to get all the corrections.
Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect WebSphere
Application Server October 2015 CPU
Otherwise:
Note: for any of the below remediations, if you are a WAS deployment, then
WAS must also be upgraded, in addition to performing your product upgrades.
Upgrade your products to version 3.0.1.6 or 4.0.7 or 5.0.2 or 6.0.1, apply the
latest ifix, and then perform the following upgrades. Request the
January 2016 CPU update for the IBM Java SDK:
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
For the 3.x releases of Rational Software Architect Design Manager and
Rhapsody Design Manager, if you cannot upgrade to 4.0.7 or 5.0 or 6.0,
contact IBM Support for guidance.
For the 2.x releases, contact IBM Support for additional details on the fix.
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.
