In some cases IBM Rational ClearCase client components using OpenSSL might be affected. The vulnerability could allow a malicious server to expose private memory of the client. ClearCase has no affected server components. Vulnerability Details CVE-ID: CVE-2014-0160 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 (i.e. server, client, agent) receiving connections using the vulnerable OpenSSL library. CVSS Base Score: 5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92322 CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N) Warning: It is strongly encouraged that you take action as soon as possible as potential implications to your environment may be more serious than indicated by the CVSS score. Affected Products and Versions IBM Rational ClearCase versions: 7.1.2 through 7.1.2.13 8.0 through 8.0.0.10 8.0.1 through 8.0.1.3 Note: Versions earlier than 7.1.2 are not affected. Not all deployments of Rational ClearCase use OpenSSL in a way that is affected by these vulnerabilities. You are vulnerable if your use of Rational ClearCase includes any of these configurations: You use the base ClearCase/ClearQuest integration client on any platform, configured to use SSL to communicate with a ClearQuest server. The perl interpreter running the integration scripts is vulnerable to a malicious server (or an attacker intercepting connections to a server). You use the UCM/ClearQuest integration on UNIX/Linux clients, configured to use SSL to communicate with a ClearQuest server. The client is vulnerable to a malicious server (or an attacker intercepting connections to a server). Note: Windows clients using the UCM/ClearQuest integration are not vulnerable. You use the Change Management Integrations for base ClearCase with ClearQuest or Rational Team Concert (RTC), or for UCM with ClearQuest or RTC on UNIX/Linux clients, configured to use SSL to communicate with a ClearQuest or RTC server. The client is vulnerable to a malicious server (or an attacker intercepting connections to a server). Note: Windows clients using the CMI integration are not vulnerable. You use ratlperl, ccperl, or cqperl to run your own perl scripts, and those scripts use SSL connections. The perl interpreter is vulnerable to attacks by a malicious network peer. Remediation/Fixes Apply an interim fix for your appropriate release of ClearCase. 7.1.2.x: Install Rational ClearCase Fix Pack 13 (7.1.2.13) for 7.1.2 plus Interim fix 1 (7.1.2.13.01) 8.0.0.x: Install Rational ClearCase Fix Pack 10 (8.0.0.10) for 8.0 plus Interim fix 1 (8.0.0.10.01) 8.0.1.x: Install Rational ClearCase Fix Pack 3 (8.0.1.3) for 8.0.1 plus Interim fix 1 for (8.0.1.03.01) 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. 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 ratlperl, ccperl, or cqperl with SSL until you apply the fixes listed above.

Some configurations of IBM Rational ClearCase may expose this vulnerability. Vulnerability Details CVE-ID: CVE-2014-0076 Description: OpenSSL could allow a local attacker to obtain sensitive information, caused by an implementation error in ECDSA (Elliptic Curve Digital Signature Algorithm). An attacker could exploit this vulnerability using the FLUSH+RELOAD cache side-channel attack to recover ECDSA nonces. This vulnerability can only be exploited locally, authentication is not required and the exploit is not complex. An exploit can only partially affect confidentiality, but not integrity or availability. CVSS Base Score: 2.1 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91990 CVSS Environmental Score*: Undefined CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:N/A:N) Affected Products and Versions IBM Rational ClearCase versions: 7.1.1 through 7.1.1.9 7.1.2 through 7.1.2.13 8.0 through 8.0.0.10 8.0.1 through 8.0.1.3 Note: Versions earlier than 7.1.1 are not affected. Not all deployments of ClearCase use OpenSSL in a way that is affected by these vulnerabilities. Your configuration is vulnerable if all of the following are true: You communicate with a server that uses ECDSA server certificates and You use client certificates with ECDSA and Your use of ClearCase includes any of these configurations: You use the base CC/CQ integration client on any platform, configured to use SSL to communicate with a ClearQuest server. You use the UCM/CQ integration on UNIX/Linux clients, configured to use SSL to communicate with a ClearQuest server. Note: Windows clients using the UCM/CQ integration are not vulnerable. You use the Change Management Integrations for base CC with CQ or RTC, or for UCM with CQ or RTC on UNIX/Linux clients, configured to use SSL to communicate with a ClearQuest or RTC server. Note: Windows clients using the CMI integration are not vulnerable. You use ratlperl, ccperl, or cqperl to run your own perl scripts, and those scripts use ECDSA client certificates to open an SSL connection to a server that uses ECDSA certificates. Notes: If your server uses other certificate types, you are not vulnerable. If you do not use client certificates, you are not vulnerable. Remediation/Fixes Apply an interim fix for your appropriate release of ClearCase. 7.1.1.x: Upgrade to Rational ClearCase Fix Pack 13 (7.1.2.13) for 7.1.2 plus Interim fix 1 (7.1.2.13.01) Note: 7.1.2.13 inter-operates with all 7.1.1.x systems, and can be installed in the same way as 7.1.1.x fix packs. 7.1.2.x: Install Rational ClearCase Fix Pack 13 (7.1.2.13) for 7.1.2 plus Interim fix 1 (7.1.2.13.01) 8.0.0.x: Install Rational ClearCase Fix Pack 10 (8.0.0.10) for 8.0 plus Interim fix 1 (8.0.0.10.01) 8.0.1.x: Install Rational ClearCase Fix Pack 3 (8.0.1.3) for 8.0.1 plus Interim fix 1 for (8.0.1.3.01) Workarounds and Mitigations You can avoid the issue as follows: Avoid using ECDSA certificates (client or server) until you apply the fixes. Disable your use of CC/CQ integrations with SSL using ECDSA until you apply the fixes. Avoid using ratlperl, cqperl, or ccperl for SSL operations with ECDSA until you apply the fixes.
