Security Bulletin
Summary
An OpenSSL vulnerability was disclosed on February 26, 2019 by the OpenSSL
Project. OpenSSL is used by IBM Rational ClearCase. IBM Rational ClearCase has
addressed the applicable CVE.
Vulnerability Details
CVEID: CVE-2019-1559
Description: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by the failure to immediately close the TCP connection
after the hosts encounter a zero-length record with valid padding. An attacker
could exploit this vulnerability using a 0-byte record padding-oracle attack to
decrypt traffic.
CVSS Base Score: 5.8
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
157514 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N)
Affected Products and Versions
IBM Rational ClearCase versions:
+----------------------------------------+------------------------------------+
| Version | Status |
+----------------------------------------+------------------------------------+
| 9.0.1 through 9.0.1.7 | Affected |
+----------------------------------------+------------------------------------+
| 9.0 through 9.0.0.6 | Affected |
+----------------------------------------+------------------------------------+
| 8.0.1 through 8.0.1.21 | Affected |
+----------------------------------------+------------------------------------+
| 8.0 through 8.0.0.21 | 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),
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.
Remediation/Fixes
Apply a fix pack as listed in the table below. The fix pack includes OpenSSL
1.0.2r.
+-------------------+---------------------------------------------------------+
| Affected Versions | Applying the fix |
+-------------------+---------------------------------------------------------+
| 9.0.1 through |Install Rational ClearCase Fix Pack 7 (9.0.1.7) for 9.0.1|
| 9.0.1.7 | |
|9.0 through 9.0.0.6| |
+-------------------+---------------------------------------------------------+
| 8.0.1 through |Install Rational ClearCase Fix Pack 21 (8.0.1.21) for |
| 8.0.1.21 |8.0.1 |
| 8.0 through | |
| 8.0.0.21 | |
+-------------------+---------------------------------------------------------+
For 8.0.x and earlier releases, IBM recommends upgrading to a fixed, supported
version/release/platform of the product.
Workarounds and Mitigations
None.
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.
