Description: Timing differences based on the validity of messages can be exploited to decrypt an entire SSL session. The exploit is not trivial, requiring a man-in-the-middle position and a long time (around 20 hours). ClearCase Remote Client is vulnerable to this attack if a single operation runs for such a long time.

Notes:
- If you use CCRC as an extension offering installed into an Eclipse shell (one not provided as part of a ClearCase release), you should update the Java™ Virtual Machine used by Eclipse to include a fix for CVE-2014-0411. Contact the supplier of your Eclipse or Java™ Virtual Machine for instructions on updating Eclipse.
- ClearCase 7.1.x for HP-UX uses the HP® JRE for J2SE™ HP-UX® 11i platform, adapted by IBM for IBM Software, Version 5.0. The fixes for this issue came in a later Java update for this platform, and are now available in a later ClearCase fix pack.
- Additional vulnerabilities in Java as used by Rational ClearCase have been published. Please review Security Bulletin: Java security vulnerabilities in ClearCase Remote Client (CVE-2014-4263, CVE-2014-4244) to determine whether these vulnerabilities apply to your deployment.
