Affected Products and Versions
IBM Rational ClearCase, versions 7.1.0.x, 7.1.1.x, 7.1.2.x, 8.0.0.x, 8.0.1.x,
in the following components:
CCRC WAN server/CM Server component, when configured to use SSL
ClearCase remote client: CCRC/CTE GUI, rcleartool, and CMAPI clients, when
using SSL to access a CCRC WAN Server/CM Server
ClearCase version Status
8.0.1 through 8.0.1.8 Affected
8.0 through 8.0.0.15 Affected
7.1.2 through 7.1.2.18 Affected
7.1.0.x, 7.1.1.x (all versions and fix packs) Affected Remediation/Fixes
The solution is to install a fix that includes an updated Java Virtual Machine
with fixes for the issues, and to apply fixes for WebSphere Application Server
(WAS).
CCRC Client fixes
Apply a prerequisite fix pack as listed in the table below, then apply a
test fix that includes an updated Java Virtual Machine.
Affected Versions Fix pack required before applying a test fix
8.0.1 through 8.0.1.7 Install Rational ClearCase Fix Pack 8 (8.0.1.8) for 8.0.1
8.0 through 8.0.0.14 Install Rational ClearCase Fix Pack 15 (8.0.0.15) for 8.0
7.1.2 through 7.1.2.17
7.1.1.x (all fix packs)
7.1.0.x (all fix packs) Customers on extended support contracts should install
Rational ClearCase Fix Pack 18 (7.1.2.18) for 7.1.2
Once your systems are running the relevant fix pack, contact Rational
Customer support for instructions to download and install the test fix.
Notes: If you use CCRC as an extension offering installed into an Eclipse
shell (one not provided as part of a ClearCase release), or you use rcleartool
or CMAPI using a Java Virtual Machine not supplied by IBM as part of Rational
ClearCase, you should update the Java Virtual Machine you use to include a fix
for the above issues. Contact the supplier of your Java Virtual Machine and/or
the supplier of your Eclipse shell.
CCRC WAN server fixes
Review the following WAS security bulletin: Security Bulletin: Multiple
vulnerabilities in IBM Java SDK affect WebSphere Application Server April 2015
CPU and apply the relevant fixes to your WAS installation and WAS profiles
used for ClearCase.
Affected Versions Applying the fix
7.1.0.x, 7.1.1.x, and 7.1.2.x Document 1390803 explains how to update WebSphere
Application Server for ClearCase CM Servers at release
7.1.x. Consult those instructions when applying the fix.
8.0.0.x 8.0.1.x Apply the appropriate WebSphere Application Server fix
directly to your CCRC WAN server host. No
ClearCase-specific steps are necessary.
For 7.0.x and earlier releases, IBM recommends upgrading to a fixed, supported
version/release/platform of the product. Workarounds and Mitigations
