Summary
OpenSSL vulnerabilities were disclosed on March 19, 2015 by the OpenSSL
Project. OpenSSL is used by cqperl and ratlperl for SSL communications.
Rational ClearQuest has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2015-0209
DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code
on the system, caused by a use-after-free error in the d2i_ECPrivateKey or
EVP_PKCS82PKEY function. An attacker could exploit this vulnerability 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/101674 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVEID: CVE-2015-0286
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
in the ASN1_TYPE_cmp function when attempting to compare ASN.1 boolean types.
An attacker could exploit this vulnerability to crash any certificate
verification operation and cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101666 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-0288
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
in the X509_to_X509_REQ function. An attacker could exploit this vulnerability
to trigger a NULL pointer dereference.
CVSS Base Score: 5
CVSS Temporal Score: See

score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-0293
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending a
specially-crafted SSLv2 CLIENT-MASTER-KEY message, a remote attacker could
exploit this vulnerability to trigger an assertion.

Affected Products and Versions
IBM Rational ClearQuest versions:
Version Status
8.0.1 through 8.0.1.7 Affected
8.0 through 8.0.0.14 Affected
7.1.2.x (all versions) Affected
Not all deployments of Rational ClearQuest use OpenSSL in a way that is
affected by these vulnerabilities.
You are vulnerable if your use of Rational ClearQuest includes any of these
configurations:
You use SSL connections in perl scripts run by ratlperl or cqperl, or by
ClearQuest hooks. In this situation, you should review all the fixes provided
by the OpenSSL project to see which ones apply to your use of OpenSSL. See the
references link below.
You integrate with ClearCase. See Security Bulletin: Vulnerabilities in
OpenSSL affect Rational ClearCase (CVE-2015-0209, CVE-2015-0286,
CVE-2015-0288, CVE-2015-0293)
Remediation/Fixes
The fix is to install a ClearQuest Fix Pack, then install an additional fix to
add OpenSSL 1.0.1m. This fix supersedes the fix that includes OpenSSL 1.0.1L
(announced in bulletin 1699040).
1) Upgrade ClearQuest
Affected Versions Fix Pack needed before applying test fix
8.0.1.x Install Rational ClearQuest Fix Pack 7 (8.0.1.7)
8.0.0.x Install Rational ClearQuest Fix Pack 14 (8.0.0.14)
7.1.2.x Customers with extended support contracts should install Rational
ClearQuest Fix Pack 17 (7.1.2.17)
2) After installing the appropriate Fix Pack, contact Rational Customer
support for instructions to download and install the additional OpenSSL fix.
You should verify applying this fix does not cause any compatibility issues.
Workarounds and Mitigations
Disable any script that uses SSL and runs in ratlperl, cqperl or ClearQuest
hooks until you apply the fixes listed above.

Affected Products and Versions
IBM Rational ClearCase versions:
Version Status
8.0.1 through 8.0.1.7 Affected
8.0 through 8.0.0.14 Affected
7.1.2 through 7.1.2.17 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 V2 (perl-based) integration client on
any platform, configured to use SSL to communicate with a ClearQuest server.
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.
You use the Change Management Integration on UNIX/Linux clients, configured to
use SSL to communicate with a change management 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. In this situation, you should review all the
fixes provided by the OpenSSL project to see which ones apply to your use of
OpenSSL. See the references link below.
Remediation/Fixes
The solution is to update to the latest fix pack. This fix pack includes
OpenSSL 1.0.1m.
Affected Versions Applying the fix
8.0.1 through 8.0.1.7 Install Rational ClearCase Fix Pack 8 (8.0.1.8) for 8.0.1
8.0 through 8.0.0.14 Install Rational ClearCase Fix Pack 15 (8.0.0.15) for 8.0
7.1.2 through 7.1.2.17 Customers on extended support contracts should install
Rational ClearCase Fix Pack 18 (7.1.2.18) for 7.1.2
7.1.1.x (all fix packs)
7.1.0.x (all fix packs)
You should verify applying this fix does not cause any compatibility issues.
For unsupported versions, IBM recommends upgrading to a fixed, supported
version/release/platform of the product.
Workarounds and Mitigations
Disable the integrations 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.
