Security Bulletin: Vulnerability in OpenSSL affects IBM Rational ClearCase (CVE-2016-2107)

Summary

OpenSSL vulnerabilities were disclosed on May 3, 2016 by the OpenSSL Project. OpenSSL is used by IBM Rational ClearCase. IBM Rational ClearCase has addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2016-2107 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information caused by an error when the connection uses an AES CBC cipher and the server support AES-NI. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to decrypt traffic.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/112854 for the current score
CVSS Environmental Score*: Undefined

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:

1. You use the base ClearCase/ClearQuest integration client on any platform, configured to use SSL to communicate with a ClearQuest server.

2. You use the UCM/ClearQuest integration on UNIX/Linux clients, configured to use SSL to communicate with a ClearQuest server.
   Note: Windows clients using the UCM/ClearQuest integration are not vulnerable.

3. On UNIX/Linux clients, you use the Change Management Integration (CMI) for base ClearCase with ClearQuest or Rational Team Concert (RTC), or for UCM with ClearQuest or RTC, or for Jira, when configured to use SSL to communicate with the server.
   Note: Windows clients using the CMI integration are not vulnerable.

4. You use ratlperl, ccperl, or cqperl to run your own perl scripts, and those scripts use SSL connections.
