Security Bulletin: Rational ClearCase is affected by OpenSSL vulnerabilities (CVE-2014-0224, CVE-2014-3470, CVE-2015-0292)

Security Bulletin


Summary

Security vulnerabilities have been discovered in OpenSSL that were reported on June 5, 2014 by the OpenSSL Project.

Vulnerability Details

CVE-ID: CVE-2014-0224
Description: OpenSSL is vulnerable to a man-in-the-middle attack, caused by the use of weak keying material in SSL/TLS clients and servers. A remote attacker could exploit this vulnerability using a specially-crafted handshake to conduct man-in-the-middle attacks to decrypt and modify traffic.

CVSS Base Score: 5.8
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93586 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:N)

CVE-ID: CVE-2014-3470

Description: OpenSSL is vulnerable to a denial of service, caused by the implementation of anonymous ECDH ciphersuites. A remote attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93589 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0292
DESCRIPTION:
OpenSSL could allow a remote attacker to execute arbitrary code on the system, caused by an error when processing base64 encoded data. An attacker could exploit this vulnerability using specially-crafted base 64 data to corrupt memory and execute arbitrary code on the system and cause a denial of service.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101670 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

Affected Products and Versions

IBM Rational ClearCase versions:

Version
Status
8.0.1 through 8.0.1.3
Affected
8.0 through 8.0.0.10
Affected
7.1.0.x, 7.1.1.x (all versions)
7.1.2 through 7.1.2.13
Affected
7.0.x
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:
  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. 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.
    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.

Remediation/Fixes

Apply a fix pack for your appropriate release of ClearCase. These fix packs include OpenSSL 1.0.1h.

Affected Versions
Applying the fix
8.0.1.x
Install Rational ClearCase Fix Pack 4 (8.0.1.4) for 8.0.1
8.0.0.x
Install Rational ClearCase Fix Pack 11 (8.0.0.11) for 8.0
7.1.2.x
Install Rational ClearCase Fix Pack 14 (7.1.2.14) for 7.1.2
7.1.0.x
7.1.1.x
Install Rational ClearCase Fix Pack 14 (7.1.2.14) for 7.1.2
  • Note: 7.1.2.14 inter-operates with all 7.1.x.x systems, and can be installed in the same way as 7.1.x.x fix packs.

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.

Important note

IBM strongly suggests that all System z customers be subscribed to the System z Security Portal to receive the latest critical System z security and integrity service. If you are not subscribed, see the instructions on the System z Security web site. Security and integrity APARs and associated fixes will be posted to this portal. IBM suggests reviewing the CVSS scores and applying all security or integrity fixes as soon as possible to minimize any potential risk.
