Security Bulletin: Rational ClearQuest affected by vulnerability in OpenSSL (CVE-2014-0160)
A security vulnerability has been discovered in OpenSSL. OpenSSL is shipped as embedded in cqperl, in some cases IBM Rational ClearQuest hooks/scripts using OpenSSL might be affected. The vulnerability could allow a malicious server to expose private memory of the client. ClearQuest has no affected server components.

Description: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the TLS/DTLS heartbeat functionality. An attacker could exploit this vulnerability to expose 64k of private memory and retrieve secret keys. An attacker can repeatedly expose additional 64k chunks of memory. This vulnerability can be remotely exploited, authentication is not required and the exploit is not complex. It can be exploited on any system (ie. server, client, agent) receiving connections using the vulnerable OpenSSL library.

Affected Products and Versions
IBM Rational ClearQuest versions:
- 7.1.2 through 220.127.116.11
- 8.0 through 18.104.22.168
- 8.0.1 through 22.214.171.124.
Note: Versions earlier than 7.1.2 are not affected.
OpenSSL is shipped as embeded in cqperl.
Rational ClearQuest does not provide any services using OpenSSL.
No server component is affected.
CQWeb relies on IHS/WAS for SSL connection, and IHS/WAS is not affected by this vulnerability.
You are vulnerable if you use OpenSSL in the perl hooks/scripts.
Apply an interim fix for your appropriate release of ClearQuest.
- 7.1.2.x: Install Rational ClearQuest Fix Pack 13 (126.96.36.199) for 7.1.2 plus Interim fix 1 (188.8.131.52.01)
- 8.0.0.x: Install Rational ClearQuest Fix Pack 10 (184.108.40.206) for 8.0 plus Interim fix 1 (220.127.116.11.01)
- 8.0.1.x: Install Rational ClearQuest Fix Pack 3 (18.104.22.168) for 8.0.1 plus Interim fix 1 for (22.214.171.124.01)
After applying the fix, additional instructions are needed for CVE-2014-0160.
- Replace your SSL Certificates
You need to revoke existing SSL certificates and reissue new certificates for affected SSL connections. You need to be sure not to generate the new certificates using the old private key and create a new private key (using "openssl genrsa") and use that new private key to create the new certificate signing request (CSR).
- Reset User Credentials
Users of network facing applications protected by a vulnerable version of OpenSSL should be forced to reset their passwords and should revoke any authentication or session related cookies set prior to the time OpenSSL was upgraded and force the user to re-authenticate.
Warning: Your environment may require additional fixes for other products, including non-IBM products. Please replace the SSL certificates and reset the user credentials after applying the necessary fixes to your environment.
Workarounds and Mitigations
Disable the ClearCase/ClearQuest integration and any customized defined use of cqperl with SSL until you apply the fixes listed above.
